The forged steel gate valve products are not only applicable to medium and low pressure, but also to high pressure. They are used in various working conditions such as in the petroleum, chemical, pharmaceutical, fertilizer, and power industries, to cut off or connect the pipeline media.
● Compact structure, elegant design, reduced-diameter flow channel. Structural features: B.B or W.B.
● The sealing surface is made of alloy steel or hard alloy, and the sealing materials are paired reasonably, and the service life is long.
● The gate plate structure type is: rigid wedge-shaped single gate plate; the surface of the valve stem has been nitrided, which has excellent corrosion resistance and friction resistance. ； The filler is made of flexible graphite, ensuring reliable sealing, flexible operation and low opening/closing torque.
● Cast steel gate valves can be equipped with various piping standards and connection methods (such as socket welding, butt welding, and threaded connection).
