Pressure Seal Gate Valve -> Flanged Pressure Seal Gate Valve For gate valve with pressure Class 600 PN100 or higher, Pressure seal bonnet is suggested for better closure, while bolted bonnet is still available for customer's option. The pressure seal design incorporates a metal-to-metal seal that becomes tighter as the pressure increases. The initial preload deforms the taper on the soft iron gasket to mate with the taper on the bonnet. The thin knife-edge on the gasket is wedged tightly between the body and the bonnet. The shallow angle insures that the gasket is sealed tightly with only a small upward force on the bonnet. Once the initial seal is created, the bodybonnet joint will remain leak free regardless of thermal or pressure conditions in the valve.After the joint has been assembled, there is no further need to adjust bonnet cap screws.

Floating Ball Valve -> Floating Ball Valve A floating ball valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body, it drifts toward to the downstream side and tightly pushes against the seat under the medium pressure to ensure sealing reliability. The floating ball valve has simple structure, good sealing performance but the seat material is required to withstand the workload since the sealing pressure is bared by the seat ring. Due to unavailability of high performance seat material, floating ball valve is mainly used in middle or low pressure application.

Swing Check Valve -> Swing Check Valve Swing check valves are the most common and best check valve for general-purpose use. Of all check valve designs, these valves produce the lowest pressure drop, when compared with other check valves of the same size. They feature a simple design that is easy to maintain.The swing check valve functions by allowing flow forces to move the disc from the closed position to the fully open position in a sweeping arc motion against the hinge-stop inside of the valve body. Due to the weight and center-of-gravity location of the disc and swing-arm assembly, the valve will return to the closed position should flow become interrupted or reversed. External counterweights mounted on the hinge pin are sometimes used to increase or decrease the reaction time and speed of the disc returning to the closed position. Seating surfaces are typically flat, which means the radial disc positioning onto the seat is not critical, except that it must be flat onto the seat. Swing check valve discs are not stable unless they are in systems with steady flow and are in the fully open position. As the dischinge assembly center of rotation is a fair distance from its pivot point, it will take a relatively long period of time for swing check valves to close upon flow stoppage or reversal. During this time, reverse-flow forces may experience a large increase in energy from flow and pressure buildup. This situation can cause high-energy water hammer when the disc slam.

Wafer Check Valve -> Dual-plate Wafer Check Valve Dual-plate check valves are are bonnetless and mounted between pipe flanges (wafer style). In this case, the valve includes two spring loaded half-moon shaped discs that rotate about their shaft. The actual designs of these valves vary between design models and manufacturers. Most have multiple flat seats. The dual-plate check valve disc has short rotational disc travel and responds quickly to flow stoppage or reversal, thus the potential for moderate water hammer does exist. It is somewhat better than the swing check valve at minimizing potential water hammer, but with a much higher pressure drop. Depending on the design, maintenance effort ranges from relatively simple to difficult. All dual-plate check valves must be removed from the line to perform maintenance due to the bonnetless design. The dual-plate check valve also results in a higher pressure drop when compared to a tilting disc check valve of the same size.

Eccentric Butterfly Valve -> Triple Eccentric Butterfly Valve The triple eccentric butterfly valve, which makes use of a metal seat, is therefore able to withstand a greater amount of pressure, compared to resilient seated butterfly valve. The seal of the eccentric disc could be either metalGraphite multi-layer design, or fully metal-to-metal design. The multi-layer design could achieve zero leakage and simple maintenance, while the metal-to-metal design is more reliable in higher temperature and pressure. Basically speaking, triple eccentric butterfly valve is both applied in shutoff or throttling service. Flanged butterfly valves have longer face-to-face dimensions and stronger structure, compared with wafer or lug type butterfly valves. The machining process is therefore more complicated than that of wafer or lugged butterfly valves. For butterfly valves size larger than 24", flanged end is recommended for longer service.

Piston Check Valve -> DINEN Piston Check Valve Piston check valves are also called lift check valves. They are essentially globe valves without the stem and top works, allowing the disc to respond to flow rates and direction. The disc has linear movement and is typically body-guided with conical seating surfaces. Springs can be added above the disc to provide more closure force when the disc returns to its closed position. Some manufacturers include externally attached equalizer piping to increase the disc opening with lower flows. The equalizer pipe is an open-pressure communication device that maintains equal pressure above the disc and in the piping downstream of the disc. Depending on the valve body configuration (Y-pattern, angle, or T-pattern), the pressure drop could be close to that of a tilting disc check valve or much higher. The disc of this check valve design is stable in any open position and can be used with a wide range of flow rates.

Flanged Globe Valve -> Cast Steel Globe Valve Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. Globe valves may be used for either isolation or throttling service, by installing the apporpriate disc: flat-seat disc for moderate throttling, cage for more severe throttling, and parabolic plug for linear flow control.Globe valves are also classified by the body: regular staight pattern, Y pattern and angle pattern. Their various configuration allow them to be installed in a variety of piping configurations.Globe valves are also supplied with three basic type of body-bonnet closures: bolted bonnet, welded bonnet and pressure seal bonnet. Bolted bonnet, the seal depends on the body-bonnet bolt preload to maintain sufficient compressive force, bolted bonnet is widely used for valves on various pressure ratings and sizes. Welded bonnet is mainly applied for small-size forged steel gate valves, suitable for applications requiring zero leakage on body-bonnet joint when carrying hazardous system fluids. Pressure seal bonnet is adopted for valves for high pressure service, typically in excess of 15 MPa (2250 psi). The body-bonnet joint seals improves as the internal pressure in the valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-bonnet joint.Globe valves are supplied with flanged ends, butt weld ends, socket weld ends and screwedwww.kolinkvalves.com

Slab Gate Valve -> Through Conduit Slab Gate Valve Through conduit slab gate valves are usually used for the oil & gas pipe-lines. Through conduit slab gate valve are manufactured with a full bore, slab gate, rising stem OS&Y and floating seats. Slab gate is a simple solid gate design, featuring metal-to-metal seal between gate and seats, to apply for the most severe service condition, including corrosive and abrasive fluid environments. A floating seat is designed to match the slab gate. A belleville spring and O-ring between each seat and body ensure a tight seal against the slab gate. The floating slab gate uses the natural force of line pressure to obtain a dynamically tight downstream seal in high-pressure differential applications. Low-pressure sealing is accomplished with an o-ring that energizes the seat and minimizes corrosion and debris build up. Common trims are available. Double block and bleed capability and automatic relief of excess body pressure are standard feature of this seat design. The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.Through Conduit Slab Gate valve design minimizes and eases the maintenance allowing for the service opera

Piston Check Valve -> Cast Steel Lift Check Valve Piston Check Valve Lift check valves are also called piston check valves. They are essentially globe valves without the stem and top works, allowing the disc to respond to flow rates and direction. The disc has linear movement and is typically body-guided with conical seating surfaces. Springs can be added above the disc to provide more closure force when the disc returns to its closed position. Some manufacturers include externally attached equalizer piping to increase the disc opening with lower flows. The equalizer pipe is an open-pressure communication device that maintains equal pressure above the disc and in the piping downstream of the disc. Depending on the valve body configuration (Y-pattern, angle, or T-pattern), the pressure drop could be close to that of a tilting disc check valve or much higher. The disc of this check valve design is stable in any open position and can be used with a wide range of flow rates.

Wafer Check Valve -> Flanged Dual-plate Wafer Check Valve Dual-plate check valves are are bonnetless and mounted between pipe flanges (wafer style). In this case, the valve includes two spring loaded half-moon shaped discs that rotate about their shaft. The actual designs of these valves vary between design models and manufacturers. Most have multiple flat seats. The dual-plate check valve disc has short rotational disc travel and responds quickly to flow stoppage or reversal, thus the potential for moderate water hammer does exist. It is somewhat better than the swing check valve at minimizing potential water hammer, but with a much higher pressure drop. Depending on the design, maintenance effort ranges from relatively simple to difficult. All dual-plate check valves must be removed from the line to perform maintenance due to the bonnetless design. The dual-plate check valve also results in a higher pressure drop when compared to a tilting disc check valve of the same size. Although most of the wafer check valves are installed between two flanges, and no need to be flanged type, some other applications may need flanged type wafer check valve for better alignment of valves. The flanged valve body could be cast or forged upon customer's requirement.

Trunnion Mounted Ball Valve -> Trunnion Mounted Ball Valve Trunnion mounted ball valves are designed for upstream sealing. The load generated by the line fluid on ball is absorbed by the trunnion bearings and is directly transmitted to the valve body, and the upstream seat driven by medium pressure drifts towards the ball to creater reliable sealing. The seat design has a built-in automatic cavity relief mechanism. Trunnion mounted ball valves have a bottom entry stem design, where the stem is inserted from inside the body. The higher the line pressure, the tighter the seal. An elastomer seal in the form of an o-ring is located at the lower end of the stem, which provides the first level of protection to the atmosphere. Valves are provided with vent and drain connections for ventingdraining of the valve cavity. Vent and drain connections can also be used for on-line affirmation of valve sealing.

Wafer Check Valve -> Lift-plate Wafer Check Valve Single-plate wafer check valves prevent reverse flow with disc movement that is parallel with the flow. With this design, the disc is always in the flow path. Discs are spring-loaded to assist in seating. These wafer type check valves are bonnetless and are installed between flanges. The type of check valve disc has very short disc travel and responds very quickly to flow stoppage or reversal, thus minimizing the potential for water hammer. It is somewhat better than the tilting disc check valve at minimizing potential water hammer, but with a higher pressure drop.

Tilting Disc Check Valve -> Tilting Disc Check Valve Tilting disc check valves produce slightly more pressure drop than swing check valves of the same size. These check valves have a single-piece disc without a hinge. In response to flow forces, the disc pivots about hinge pins that are located within the geometry of the disc and slightly above the center-line of the valve body. Due to the disc rotating onto the seat, the sealing surfaces must be conical. Some tilting disc check valves include a counterweight on the disc, dramatically increasing the disc stability with lower flow rates. Tilting disc check valves were designed specifically to minimize the potential for high-energy water hammer. This objective is accomplished by locating the disc center of rotation a short distance from its pivot point, thus allowing the disc to quickly close with flow stoppage or flow reversal. Although it is best to size this valve to be fully open, the disc is reasonably stable under some less than full-open flow conditions. When it comes to maintenance, tilting disc check valves are more challenging than swing check valves. To keep seat leakage to a minimum, the conical seating surfaces of the disc and in-body seat must mate well, and the disc pivot location must be precise.

Pressure Seal Gate Valve -> Pressure Seal Gate Valve, BW End For gate valve with pressure Class 600 PN100 or higher, Pressure seal bonnet is suggested for better closure, while bolted bonnet is still available for customer's option.  The pressure seal design incorporates a metal-to-metal seal that becomes tighter as the pressure increases. The initial preload deforms the taper on the soft iron gasket to mate with the taper on the bonnet. The thin knife-edge on the gasket is wedged tightly between the body and the bonnet. The shallow angle insures that the gasket is sealed tightly with only a small upward force on the bonnet. Once the initial seal is created, the bodybonnet joint will remain leak free regardless of thermal or pressure conditions in the valve.After the joint has been assembled, there is no further need to adjust bonnet cap screws.

Slab Gate Valve -> API Through Conduit Gate Valve Through conduit slab gate valves are usually used for the oil & gas pipe-lines. Through conduit slab gate valve are manufactured with a full bore, slab gate, rising stem OS&Y and floating seats. Slab gate is a simple solid gate design, featuring metal-to-metal seal between gate and seats, to apply for the most severe service condition, including corrosive and abrasive fluid environments. A floating seat is designed to match the slab gate. A belleville spring and O-ring between each seat and body ensure a tight seal against the slab gate. The floating slab gate uses the natural force of line pressure to obtain a dynamically tight downstream seal in high-pressure differential applications. Low-pressure sealing is accomplished with an o-ring that energizes the seat and minimizes corrosion and debris build up. Common trims are available. Double block and bleed capability and automatic relief of excess body pressure are standard feature of this seat design. The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.Through Conduit Slab Gate valve design minimizes and eases the maintenance allowing for the service operations.

Floating Ball Valve -> Floating Ball Valve A floating ball valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body, it drifts toward to the downstream side and tightly pushes against the seat under the medium pressure to ensure sealing reliability. The floating ball valve has simple structure, good sealing performance but the seat material is required to withstand the workload since the sealing pressure is bared by the seat ring. Due to unavailability of high performance seat material, floating ball valve is mainly used in middle or low pressure application.

Eccentric Butterfly Valve -> High Performance Butterfly Valve High Performance Butterfly Valves have either resilient disc or seat seal, which is replaceable. Compare to the rubber lined butterfly valves, the offset design of the high performance butterfly valve increases the valves sealing ability, decreases its tendency to wear and lengthen its service life.  Lug type butterfly valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and nuts. The valve is installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side.A lug type butterfly valve used in dead end service generally has a reduced pressure rating. For example a lug type butterfly valve mounted between two flanges has a 150 psi pressure rating. The same valve mounted with one flange, in dead end service, has a 75 psi rating.

The multi-layer design could achieve zero leakage and simple maintenance, while the metal-to-metal design is more reliable in higher temperature and pressure. Basically speaking, triple eccentric butterfly valve is both applied in shutoff or throttling service. Wafer type is the common style of butterfly valve and is less expensive than the lug type. The wafer butterfly valve is installed between two flanges. The valve is kept in place by using bolts or studs and nuts from flange to flange. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve.

Eccentric Butterfly Valve -> Cast Steel Flanged Butterfly Valve The triple eccentric butterfly valve, which makes use of a metal seat, is therefore able to withstand a greater amount of pressure, compared to resilient seated butterfly valve. The seal of the eccentric disc could be either metalGraphite multi-layer design, or fully metal-to-metal design. The multi-layer design could achieve zero leakage and simple maintenance, while the metal-to-metal design is more reliable in higher temperature and pressure. Basically speaking, triple eccentric butterfly valve is both applied in shutoff or throttling service. Flanged butterfly valves have longer face-to-face dimensions and stronger structure, compared with wafer or lug type butterfly valves. The machining process is therefore more complicated than that of wafer or lugged butterfly valves. For butterfly valves size larger than 24", flanged end is recommended for longer service.

Resilient Seated Butterfly Valve -> Pinless Center Line Butterfly Valve  Resilient seated butterfly valve, uses the flexibility of rubber seat, could easily achieve zero leakge, therefore is a widely applied valve in oilfield, agriculture, water & waste water and mining industries. Due to its rubber lined body materials, it is usually used in low pressure lines.   Pinless design eliminates potential leakage point at the discshaft joints, and perform better in high corrosive media, compared to normal pined disc butterfly valve.  Lug type butterfly valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and nuts. The valve is installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side.A lug type butterfly valve used in dead end service generally has a reduced pressure rating. For example a lug type butterfly valve mounted between two flanges has a 150 psi pressure rating. The same valve mounted with one flange, in dead end service, has a 75 psi rating.

Cryogenic Ball Valve -> Stainless Steel Cryogenic Ball Valve Applications such as liquefied natural gas and other low temperature fluids, present special extreme temperature valve functionality challenges. Valves designed for cryogenic services, are specially prepared and designed to overcome these challenges. Appropriate component materials such as 304SS (CF8) and 316SS (CF8M) are normally used for body and trim, offering superior impact strength, and excellent corrosion resistance and heat loss properties. An extended bonnet and gas column design is also normally adopted to provide thermal insulation at the stem seal and stem packing area. At sufficient length, this design feature places the functionality of the stem seal in the vapor zone of the liquid media providing safe and continuous valve operation. A variety of body, trim, seat, and seal materials are available for use in cryogenic service. Customer specified options, such as body cavity vent hole, special extension lengths, and materials are also available upon request. Features of Stainless Steel Cryogenic Ball Valves: 1.Positive ball cavity relief to prevent dangerous overpressure due to thermal expansion.2.Pressure safe stem assembled inside the body for blowout prevention.3.Zero leak packing incorporating bellville spring live loaded packing assures zero leakage and high cycle life.4.Effective bonnet extension conforms to industry standards for wall thickness and lengths reducing heat transfer and frost free.

Pressure Seal Globe Valve -> Pressure Seal Globe Valve Pressure seal bonnet is suggested for better closure in high pressure condition, while bolted bonnet is still available for customers option. The pressure seal design incorporates a metal-to-metal seal that becomes tighter as the pressure increases. The initial preload deforms the taper on the soft iron gasket to mate with the taper on the bonnet. The thin knife-edge on the gasket is wedged tightly between the body and the bonnet. The shallow angle insures that the gasket is sealed tightly with only a small upward force on the bonnet. Once the initial seal is created, the bodybonnet joint will remain leak free regardless of thermal or pressure conditions in the valve.After the joint has been assembled, there is no further need to adjust bonnet cap screws.
