ZW205 Lead-Free Pressure Relief / Pressure Sustaining Valve

Technical Data | Related Products

Manufactured by: Zurn Wilkins
Model: ZW205

ZW205 pilot operated pressure relief/pressure sustaining automatic control valve can be plumbed in two different ways:

  1. Mounted on a branch line - ZW205, in a relieving function, will open when the pressure exceeds a pre-set limit, relieving pressure from the system.
  2. Mounted inline - ZW205, in a sustaining function, maintains a minimum upstream pressure by closing off as the upstream pressure begins to drop.

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).
  • Once the upstream pressure exceeds the set point of the pilot assembly, the main valve will open and relieve the excess pressure (relief).

Available with an optional checking feature.
