High Temperature High Pressure Flange Type Wedge Gate Valve For Power Station
Our wedge gate valve are widely used in many industries including:
Process Industry- Oil, Chemical, Petrochemical , Refining, Pulp & Pater, Pharmaceutical and Food Processing.
Power Industries- Nuclear, Fossil Fuel, Combined Cycle, Cogeneration and District Heating.
In addition, our valves are used for Ship-building, LNG Tanker Carriers, Offshore Platforms, Water Treatment, Mining and more.
Stellite deposited Seal face
High quality deposits of Stellite 6 and other hardfacing alloys are assured by the use of the following state of the art technology: controlled preheating, automatic Plasma Arc hardfacing equipment and a controlled cooling process.
What is flexible wedge
The flexible wedge is a one piece, fully guided cast wedge with a central hub to allow the seating faces to move relative to each other thus compensating for distortion of the body seats due to thermal expansion or piping loads.
Seat ring and wedge seating surfaces are set on a 5 degree angle from vertical to minimize sliding contact of the wedge and seat ring during opening and closing. Wedging actions help affect a tight seal in low differential pressure services.
Flexible wedge construction resists wedge sticking or binding in services where the valve may be closed when hot and opened when cold. Seating surfaces are hardfaced to provide high cycle capability in very high differential pressure services.
