Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed to reduce high upstream pressures to a safe and usable downstream pressure, critical in fire safety and industrial applications. Its pilot assembly precisely modulates the main valve to maintain a constant downstream set pressure, automatically sealing shut to prevent downstream damage.

This valve features an epoxy-coated internal and external finish for enhanced corrosion resistance, ensuring durability and a longer lifespan. The included isolation valves and pressure gauges simplify monitoring and maintenance.

Construction & Operation

  • Features a globe body design with an 8 inch Class 300 Flange end connection.
  • The valve body and bonnet are constructed from Ductile Iron ASTM A536, with internal components like the disc guide, disc, stem, and spring made from Stainless Steel.
  • The diaphragm is Nylon Reinforced Buna-N, and the seat is Bronze-N.
  • The pilot system maintains the downstream pressure within the adjustable range of 15-120 PSI.
  • Included components such as a "Wye" Type Strainer, isolation valves, and inlet/outlet pressure gauges facilitate quick and easy maintenance.

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