Introduction
Hydraulic pressure seal gate valves are uniquely designed for demanding conditions in sectors of power plant, refinery, oil & gas ,etc.
It has superior ruggedness and assured longevity under maximum pressure rating of CL4500 and working temperature of 600 °C.
Features-1
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.
