Cast steel gate valves offer the ultimate in dependable service for steam, air, gas, oil, oil vapor, and high pressure installations. All have straight-through ports to assure minimum turbulence, erosion, and resistance to flow. They are available in a wide variety of trims.
The cast steel gate valves are on-off valves manufactured according to API, ANSI, ASME standard, for industrial applications.
Product Features:
1. All the Seat faces are hardfaced, ground, and lapped to a mirror finish to ensure the reliable sealing performance.
2. Outside screw and yoke, bolted bonnet , flexible or solid wedge, rising stem with top sealing.
3. Body: Body is cast to provide liberal strength to meet operating conditions and to permit unobstructed flow. Turbulence, erosion and pressure drop are minimized.
4. Integral Yoke & Bonnet: Some designs incorporate a two-piece bonnet and yoke. All bonnet assemblies are cast and finished to the same exacting tolerances as the bodies for accurate alignment of stems and ease of sealing. Bonnet joint varies from flat face gasket-joint to ring-type bonnet joint, depending on class.
5. Seat Rings: Seat rings are seal welded to eliminate leak path behind rings and for long trouble-free service. The surfaces are precision ground to fit accurately with the disc.
6. Disc: Relia one piece flexible disc provides accurate alignment of mating seating surfaces so the valve can absorb piping strains without leakage. Also, it avoids any tendency to stick in the seated position.
7. Stem: The tee-head disc-stem connection prevents lateral strain on the stem for smooth, easy operation. Accurately cut threads engage the yoke sleeve for positive control of disc position.
