Wilkins ZW205 Pilot Operated Water Pressure Relief Valve, Lead-Free*

The Zurn Wilkins Model ZW205 Pilot Operated Pressure Relief Pressure Sustaining Valve is designed for applications where it is critical to maintain a pre-determined upstream pressure. The pilot assembly reacts to changes in upstream pressure allowing the main valve to modulate between the closed and open position, maintaining desired upstream set pressure. As long as the upstream pressure is below the set point of the pilot assembly, the main valve will stay in the closed position (sustaining); however, once the upstream pressure exceeds the set point of the pilot assembly, the main valve will open and relieve the excess pressure (relief).
