Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed for applications requiring the reduction of high inlet pressures to a safe and stable outlet pressure. This model features an 8-inch IPS grooved end connection and a globe style body.

The pilot assembly reacts to changes in downstream pressure, allowing the main valve to modulate between the closed and open position, ensuring a constant downstream set pressure. The valve also seals shut automatically once the pilot setting is reached to prevent downstream damage. This Model ZW209 comes standard with epoxy coating internally and externally for enhanced corrosion protection, along with isolation valves and pressure gauges for simplified maintenance.

Features

  • Maintains a constant downstream set pressure, independent of flow rate.
  • Epoxy coated ferrous surfaces, internally and externally, for corrosion protection.
  • Standard inclusion of a "Wye" Type Strainer for the pilot assembly.
  • Includes inlet and outlet pressure gauges for easy monitoring and diagnostics.
  • Equipped with isolation valves for quick and easy maintenance or repair.
  • Features a Pilot on Reverse Side (RV) configuration.
  • Durable Stainless Steel seat.
