Y type Pressure Relief Valve DN65

Pressure Release Valve Y type Hydraulic and Automatic Control Valve - Pressure Relief, Sustaining, Y type Pressure Relief Valve can maintain upstream pipe pressure. It is applied for pressure relief, sustaining, and back impact problems. During operation, through pilot to sense the valve inlet pressure and control the open/close of the valve. When the input pressure is over the preset value, valve will quickly open and maintain the pressure in the pipe. After pressure relief, the valve will close slowly to prevent impact happening. If a check feature is added, and a pressure reversal occurs, the downstream pressure is admitted in the main valve cover chamber closing the valve to prevent return flow. The function of Hydraulic Control Valve –Pressure Relief Valve Pressure Relief Valve  Pressure Relief Valve protects against excessive pressure in pump stations, distribution systems, and transmission mains by opening when the inlet pressure exceeds a preset value…
