Shanghai Huanyao Valve Co., Ltd.

The main safety valve is mainly used in power station boilers, pressure vessels, and temperature and pressure reducing devices to prevent the pressure from exceeding the maximum allowable pressure value and ensure the safe operation of the equipment. When the medium pressure rises to the set pressure, the impulse safety valve opens, and the medium enters the piston chamber of the main safety valve from the pulse tube, pushing the piston down, causing the valve to open automatically. When the impulse valve closes, the valve disc automatically closes again. The sealing surface is overlay-welded with cobalt-based chromium-nickel stainless steel, and the valve disc is heat treated to improve wear resistance and erosion resistance.
