Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed for many applications, including fire safety systems, where the reduction of high inlet pressures to a safe and stable outlet pressure is required. The pilot assembly reacts to changes in downstream pressure, allowing the main valve to modulate and ensure a constant downstream set pressure, sealing shut once the pilot setting is reached to prevent downstream damage. Pressure regulation is independent of flow rate.

Standard Features

  • Epoxy coating: All internal and external ferrous surfaces are factory applied with a high quality, fusion epoxy coating, which is FDA Approved for superior corrosion protection.
  • Pilot assembly: Features a "Wye" Type Strainer, isolation valves, inlet and outlet pressure gauges, and copper tubing with brass fittings for quick and easy maintenance and repair.
  • Pilot control: Is field adjustable with a spring range of 15-120 psi.

Construction Materials

  • Main Valve Body: Constructed from Ductile Iron ASTM A536 for durability.
  • Main Valve Bonnet: Ductile Iron ASTM A536
  • Disc Guide: Stainless Steel
  • Seat: Stainless Steel
  • Disc: Buna-N Rubber
  • Diaphragm: Nylon Reinforced Buna-N for reliable performance.
  • Stem: Stainless Steel
  • Spring: Stainless Steel

The closing speed control (optional) on this valve should always be open at least three (3) turns off its seat.
