Globe valves are most commonly used where throttling or both throttling and shut-off are required. Because of high pressure drop in globe valves, on-off service usage is usually confined to the applications where the valve is normally closed and the pressure drop is not important when the valve is open. The flow control element – the disc – of the globe valve moves along the axis of media flow path and it is always in the fluid path. Because the globe valve is design for both throttling and shut-off, they should not be used for prolonged periods of throttling at less than 10% open, Internal damage can occur.

Plug Valves are the valves which have cylindrical or conical tapered “plugs” which can be rotated inside the valve body to control flow through the valve. The plugs have one or more hollow passageways going sideways through the plug. So, the fluid can flow through the plug when the valve is open, i.e. hollow passage way will coincide with inlet & outlet. Plug Valves are simple and often economical. The 2-ports – 2-way plug valve is with two position at 90° open to allow the flow and close to stop the flow. It is possible to have more than 2-way like ball valves. In the 3-way valve, flow from one port could be directed to either second port or third port. A 3-way plug valve could also be designed to shift flow between ports 1 and
2, 2 and 3, or 1 and 3 and possibly even connected all 3-ports together. 3-way valve have L-port and T-Port. L-port will connect the middle port as 1 with 2 and rotating plug at 180° will connect port 1 with 3. Plug rotating at 90° will close the ports. T- port type valve will connect middle port as 1 with ports 2 & 3 and also will work like L-port.

Features:

• Full bore – pressure balanced – tapered – lubricated plug valve to satisfy the increasing demands of its customers for a plug valve with similar feature to those of a ball valve. Thus the full bore plug valves can be used in critical services such as slurries and mining or in pig gable gas pipelines.
• Unwanted deposits, that can be collected on the taper plug surface, will be cut off during the opening and closing of the valve, ensuring the fluid contact surfaces are kept clean and guaranteeing regular operation of the valve without risk of seizure.
• Applying a hard facing overlay of Stellite, Inconel 625 or tungsten carbide can enhance the metal to metal seat of the valve.
• The operating system of pressure balanced plug valves consists in the pressure equalization between the port area and the top/bottom of the plug, providing the plug with two holes. The upper hole connects the plug port area with the top of the plug, while the lower maintains the pressure equalization between the port area and the bottom of the plug. In this way the line pressure cannot lock the plug against the body taper, causing the valve to seize. Subsequently the Pressure Balance operating system permits a predictable torque even after a prolonged time in the open or closed position.
• Superior, longer lasting In-line Sealing.
• No Cavities, Reduce risk of Contamination.
• The tapered plug held firmly in to its tapered seat but can be so adjusted that complete leak tightness is achieved together with smooth valve operation.
• Plug Valves are available in Four Different Patterns – Viz. Full Bore – Short Pattern – Regular Pattern and Venturi Pattern.

Diaphragm Valves are the valves which have body with one or more ports, an elastomeric diaphragm and a weir or saddle or a seat on which the diaphragm seats and closing the valve. There are two types of Diaphragm Valves, one type seals over a weir or saddle - Is called Weir type (Reduced bore type) and other seals over a full diameter bore seat. is called Full bore type, Or Straight through type valve. The weir type valves are used in most common in process application and full bore type valves are used for slurry application to reduce blocking issue, but exists also as a process valves. Diaphragm valves can be manual hand wheel or pneumatic electric hydraulic actuated automated. Their application is generally as shut-off valves in process system and new designed is suited for regulating and controlling process flow. They are used for Industrial chemical plants, food and beverage, pharmaceutical and biotech industries. These valves were developed for Industrial applications, but later on the design was adapted for use in the bio-pharmaceutical industries by using compliant materials that can withstand sanitizing and sterilizing methods.

Features : Diaphragm valves are Dip proof Closure even with suspended solids in media. Universal use due to individual combinations of body and diaphragm materials adapted to media. Bonnet(hood) &Diaphragm pressure (compressor) piece are not in contact with the medium. Lift restriction as standard. Numerous actuation type of manual as well as automation are available. The diaphragm Valves offer the most corrosion protection possible at costs less than Hastelloy, Titanium, Zirconium and Tantalum. These valves are designed for highly-corrosive media, abrasion resistance, contamination & hot acids including hydrochloric acid, sulfuric acid, Sour gas(H2S), acetic acid & nitric acid. Aseptic Diaphragm Valves available which are the most important control components in Todayâs biopharmaceutical process s

Because of Gate Valves ability to cut through liquids, gate valves, with modified gate, are often use in petroleum industries, specialty for extremely thick fluid, often knows as Knife Gate valves, is being used to cut through the liquids. Knife gate valves are ideal for applications that involves abrasive and corrosive slurries, powders or coarse substances. One of the benefit that these valves have is that the metal parts of the valves are not in contact with the slurry when open, only easily replaceable rubber ring sleeve or secondary seal touch the medium. The ring sleeves and seals are placed in the valve housing to seal against gate when the valve is closed and seals against each other when the valve is open. This tight seal contains the high internal line pressure. Double seated design provides bi-directional flow and tight shut off. Any material/medium discharged between the sleeves during stroking open or close is collected within the containment area of the valve body and drained via the multiple flushing ports in the body. The knife gate valves are also available with metal to metal seat with Uni-directional as well as bi-directional types.

Check Valves are the valves which normally allow the fluid (liquid or Gas) to flow through it in only one direction & hence they are also called as Non-return valves or One way valves or Clack valves.

Check valves are of two ports valves, one for inlet and other for outlet. There are various types of check valves, used in a wide variety of applications. Check valves work automatically with the fluid parameters. Check valve are not controlled by any person or any external control like any type of actuator. They do not have any valve handle or stem.
An important concept of the check valves are the Cracking Pressure which is the minimum upstream pressure at which the valves will operate. Typically, the check valves are designed for and can therefore be specified for a specific cracking pressure.

Check valves are helping the pumps to discharge flow smoothly without any additional load or uneven hammering to pump impellers. Check valves are also often used when multiple gases are mixed in to one gas stream. A check valve is installed on each of the individual gas streams to prevent mixing of gases in the original sources. For example: if a fuel and an oxidizer are to be mixed, then check valves will normally be used on both the fuel and Oxidizer sources to ensure that the original gas cylinders remain pure and helping to be nonflammable – safety.

There are various types of check valves : viz.

• Swing Check Valve or tilting disc check valve – the movable part as disc swings on a hinge or trunnion, allowing the inlet fluid and blocking the returning of flow towards inlet. Disc is working as leak proof seat on the inlet port from inside so that with the help of fluid pressure it allows to flow, but with the help of return flow pressure it blocks the flow towards inlet. The stroke of this swing disc can be controlled by external screw stopper mechanism to control the flow as well.
• Lift Check Valve – the plug is seating on a port after inlet towards outlet side.
• This also works with the help of pressure same as swing check, the plug is getting lift upward and allowing the fluid to pass through and closing the port with the returned fluid pressure.
• Ball check valve – there is ball in place of plug and working same function as lift plug.
• Ball check with Spring loaded or plug check with spring loaded are also provided where the pressure difference is too low and spring will help to keep it in shut position.

Pressure Safety Valves are the valve mechanisms which automatically releases a substance when the pressure exceeds preset limit, in like a steam boiler, pressure vessel, pressure pipelines, etc. Pressure Safety valves are normally used in steam and air or gas pressure systems. It automatically blows, when the pressure in the system exceeds pre-set limits.

Pressure Relief Valves are the valve mechanisms which automatically control or limit the pressure in the system or vessel which can be built up by process upset, instrument or equipment failure or fire. The pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out from the system. The relief valve is designed or set to open at predetermined set pressure to protect pressure vessels and other equipment from being subjected to pressures that exceeds their design limits. When the set pressure exceeds, the relief valve the path of least resistance, as the valve is forced open and the portion of the fluid id diverted through the auxiliary route. The diverted fluid is usually routed through a piping system, known as a flare header or a relief header to a central. Sometime it is being called as Bypass valve.

• Pressure Safety valves (PSV) and Pressure Relief Valves (PRV) are note the same thing.
• Pressure Safety valve is an automatic system that release the static pressure on a gas by usually opens completely, accompanied by popping sound. Pressure Safety Valve have manual lever to activate the valve in case of emergency.
• Pressure relief valve is an automatic system that is actuated by the static pressure in a liquid filled vessel or pipeline, specifically opens proportionally with increasing pressure.

Features :

• The basic spring loaded safety/relief valve, referred to as Standard or Conventional, is a simple, reliable self-acting device, that provides overpressure protection.
• The basic elements of design, consists of a right angle pattern valve body with the valve inlet connection or nozzle, mounted on the pressure containing system. The outlet connection may be screwed or flanged, however in some application like compressed air system, the safety valve will not have outlet connection but just a vent holes directly to atmosphere.
• The closing force on the seat disc is provided by spring, typically made from carbon steel.
• The amount of compression on the spring is usually adjustable, using the spring adjuster to alter the pressure at which the disc is lifted off its seat.
• The three dimensions that relates the discharge capacity of safety/relief valve are: the flow (bore) area, the curtain area (between seating surfaces) and the discharge or orifice area. All are correctly designed to function well. There are wide range of safety/relief valves available to meet the many different applications and performance criteria demanded by different industries.
