Pressure Regulator Valve with Downstream Surge Protection

Pressure regulator valve ZW209Q with downstream Surge Protection provides both functions in one valve. Standard features ease maintenance and repair to provide the lowest ownership costs. This PRV valve will rapidly close to protect the downstream piping system if there is a sudden surge in downstream pressure. The pressure reducing pilot assembly reacts to changes in downstream pressure allowing the main valve to modulate between the closed and open position ensuring a constant downstream pressure within tight tolerances.
