Cast Steel Gate valveManufacturer
S J cast steel gate valve is manufactured to various low pressure service standards. It is designed with wheel-shaped handle and metal-to-metal seat seal. The flange end gate valve consists of a closing element called wedge or disc, which allows or blocks the process fluid to flow through the valve body.
1. S J cast steel gate valve 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.S J cast steel gate valveBody is cast to provide liberal strength to meet operating conditions and to permit unobstructed flow. Turbulence, erosion and pressure drop are minimized.
4.S J cast steel gate valve 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.S J cast steel gate valveSeat 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.S J cast steel gate valveDisc: 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.S J cast steel gate valveStem: 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.
