Product Profile of Cast Steel Pressure Seal Gate Valve

Cast Steel Pressure Seal Gate Valve is available in sizes from 2" to 12" and is used for stop valves fully opened or fully closed and are not normally considered for throttling purposes, but more for slurries, viscous fluids, etc. The Valve has stem connection to the gate that is a t-head design which is integral with the stem and the accuracy in the dimensions and finishes assure a long life with a good tightness in the packing area, resulting in lower fugitive emissions. The Valve comes equipped with a backseat bushing and is offered with a solid flexible gate that has a tapered H cross-section. The Valve has flexible wedge that is cast or machined with a circumferential groove to allow the seating surfaces to move independently and adjust to movement of the body seats and is suitable for steam or other high temperature services and is useful to prevent sticking where valves are closed when hot and opened when cold. The Cast Steel Pressure Seal Gate Valve has seat rings which are designed to reduce and/ or prevent any turbulence and avoid damages due to the corrosion and the seat rings are forged or rolled in one piece, and then seal welded and overlaid, if required.
