  • 1.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 due to the cavity pressure;

    3.The sealing surface of the valve disc and the valve seat is made of stellite cobalt-based hard alloy surfacing;

    4.The valve stem has optimized strength and scratch resistance.

    5.Closing wedge can be designed into single wedge, double wedge, parallel double wedge;

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

    7.Hydraulic actuators are tailored to ensure tight closure.
