| Application | 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). |
