1.Alloy steel pressure seal gate valves adopt unobstructed flow channel, which greatly reduces the flow resistance coefficient and energy loss.

2.The middle cavity of the valve adopts a pressure self-tightening sealing structure against the rising sealing force.

3.The sealing surface of the valve disc and the valve seat is made of stellite cobalt-based hard alloy surfacing, which has high temperature resistance, corrosion resistance and scratch resistance.

4.After quenching and tempering and surface nitriding, the valve stem has optimized strength and scratch resistance.

5.Bypass valves are available to cope with over pressurization and pressure locking.
