Forged steel gate valve
Forged Steel Gate Valve
Introduction of Forged Steel Gate Valve
- Two inch and smaller valves are available with threaded or socket weld ends as standard.
- Made from one piece, die-forged bodies.
- All internal surfaces are accurately machined to provide maximum performance.
- Renewable seat rings are made from hardened stainless steel, faced with Stellite.
- The wedge is forged, hardened, ground, and lapped to ensure leak free sealing.
- Fully guided wedge, precision machined body channels, for accurate, repeatable seating alignment.
- Graphite packing, complete with braided graphite filament yarn anti-extrusion rings, is standard.
- Standard body and bonnet materials are carbon steel (ASME SA105), alloy steel (ASME SA182 Gr. F11) and stainless steel (ASME SA182 Gr. F316) Trim for steel valves is 13% chrome stainless steel. 316 stainless steel valves have 316 trim.
- Code compliance with ASME B16.34 and the ASME boiler and pressure vessel code, Section I.
