41-03 Hydraulic Control Valve – Pressure Relief Valve
Model 41-03 Hydraulic and Automatic Control Valve - Pressure Relief, Sustaining, BackPressure 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 41-03 Hydraulic Control Valve –Pressure Relief Valve
1. Sensitive and accurate pressure control function
2. Quickly open valve and ensure pipe pressure
3. Slow shut-off design and impact prevention
4. Completely automatic operation
5. Installation Direction – Vertical or Horizontal Direction
Sustaining Valve
41-03 can be used as sustaining valve by installing it between upstream high pressure water supply and downstream big flow rate demand. It can maintain upstream supply pressure to avoid over flow rate problem which will lead upstream supply pressure loss.
