Additional Details

The Zurn Wilkins Model ZW205 is a pilot-operated pressure relief and pressure sustaining valve designed for applications where it is critical to maintain a pre-determined upstream pressure.

It modulates between closed (sustaining) and open (relief) positions, opening to relieve excess pressure when upstream pressure exceeds the set point and closing when it returns to acceptable limits.

Standard Features

  • Blue Epoxy Coated, FDA Approved
  • Pilot Assembly includes "Wye" Type Strainer, Closing Speed Control (for sizes 1 1/4" - 4"), and Isolation Valves
  • Inlet Pressure Gauge
  • Copper Tubing and Brass Fittings

Materials

  • Main Valve Body: Ductile Iron ASTM A536
  • Main Valve Bonnet: Ductile Iron ASTM A536
  • Disc Guide: Stainless Steel
  • Seat: Stainless Steel
  • Disc: Buna-N Rubber
  • Diaphragm: Nylon Reinforced Buna-N
  • Stem: Stainless Steel
  • Spring: Stainless Steel

Standards Compliance

  • ANSI/AWWA C530
  • Meets NSF/ANSI/CAN 61 requirements (0.25% MAX. WEIGHTED AVERAGE LEAD CONTENT)

Caution: The recommended installation orientation for Automatic Control Valves (ACVs) is horizontal, with the valve cover up. 6" and larger valves should only be installed horizontally to prevent difficulty in bleeding air out of the cover and performing maintenance on vertically installed valves.
