Wenzhou JOEPAI Valve Co., Ltd. is a professional valve manufacturer. The full bore design of the Cast Steel Wedge Gate Valve ensures smooth flow of the medium, and the sealing pair is precision ground to maintain good sealing performance and opening and closing stability for a long time. Optional soft seal or metal seal structure, can accept multiple media and complex construction conditions.
What is cast steel valve? Cast Steel Wedge Gate Valve is one of many valve types, manufactured from cast steel (carbon steel). The applicable temperature for cast steel valves is ≤ 425 ℃, and the applicable medium is water, oil, natural gas, etc. The commonly used cast steel valve series products include cast steel ball valves, cast steel gate valves, cast steel butterfly valves, cast steel check valves, cast steel globe valves, cast steel filters, etc.
Features: The gate is vertically adjustable for opening and closing, only fully open and fully closed, and cannot be adjusted or throttled;
Wedge guiding minimizes seat rubbing and scuffing resulting in long cycle
life.
Designed to ASME B16.34.
Body made of superior strength forgings and optional cast steel.
Diantai stem seal offers tight seal with little to no maintenance over long
periods of time.
Optional live-loading of packing.
Non-rotating stem.
Hardfaced seating faces resist erosion.
Other sizes and pressure classes available. Contact the company for

The opening and closing component of a Cast Steel Wedge Gate Valve is the gate plate, and the direction of movement of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.
The gate valve has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces that form a wedge shape. The wedge angle varies with the valve parameters, usually 5 °, and 2 ° 52 'when the medium temperature is not high.
