Our Products
Our product range contains a wide range of Non Return Valve, Gate Valve, Globe Valve and Pressure Reducing Valve
We offer complete range of non return valves to suit the various application in process industry. The disc check type non return valve are design to fit between the flanges & prevent the reverse flow in the lines.
The Disc check type non return valve gets opened by pressure of fluid passing through it and gets closed by the spring when flow stops or whenever there is reverse flow.
Available Sizes: 15NB to 150NB
VOLFRAM make Cast Steel Flex Gate Valves are tight sealing, easy operation, isolation valves for liquid and gaseous fluids over a wide range of line pressures and temperatures.
Gate valves are of rising stem, outside, screw and yoke (OS & Y) and with Bolted Bonnet construction. The rising stem indicates open or close position of the valve. The outside screw ensures easy lubrication and prevents corrosion and erosion by line fluids. On request, valves can be supplied with special features like NACE Requirement, Radiography, Magnetic Particle Test, LGC Test and for Oxygen Service etc.
Body & Bonnet: The body is designed for strength to meet the operating conditions and contoured to minimize erosion and resistance to flow. The bonnet is provided with renewable seat arrangement.
Flexible Wedge: The one piece, case flexible wedge minimizes stress concentration and assures tight sealing over a wide range of different operating temperature and pressure conditions.
Body Seat Ring: The seat ring is welded to provide a bubble tight joint.
Back Seat Arrangement: The back seat is designed to relieve back pressure on the stem packing when fully seated.
Seating Surface: Gate valves can be offered with stellite seat, if specified. Stellated seat ring provides increased resistance to ware, abrasion and erosion of the sealing surface.
Gland Arrangement: The stuffing box holds an adequate packing rings to enhance gland tightness and increases the life of packing rings.
Flanged: ASME B 16.5 Raised Face
Butt Weld: ASME B 16.5 to suit the corresponding pipe schedule.
Design : API 600
Face to Face / dimensions : ASME B 16.10
Testing : API 598
Valves can also be offered with IBR certification.
Valves can be supplied with accessories like extended Stem Arrangement, Gear Operation, Pneumatic and Electric Actuators, Chain Wheel Arrangement, Drain Plug and By-pass Arrangement.
VOLFRAM make Valves are tight sealing, easy operation, regulation valves for liquid and gaseous fluids over a wide range of line pressures and temperatures.
Globe valves are of outside screw & yoke (OS & Y) and with bolted bonnet construction. The outside screw ensures easy lubrication and prevents corrosion and erosion by line fluids.

The Samson make Type 41-23 self-operated universal pressure reducing regulator is a standard size regulator (1/2" - 4") designed to work in all general industrial applications. A pressure reducing valve is used for controlling the downstream pressure (p2) to an adjusted set point. The design of a pressure reducing regulator valve is to close when the downstream pressure rises above a set value.
These valves are self-operated in that the downstream pressure being controlled is tapped downstream of the Pressure Reducing Valve and transmitted via a control line to the operating diaphragm of the Type 41-23 where it is converted into a positioning force.
