Description

The Zurn Wilkins Model ZW209 is a 4-inch pilot-operated pressure reducing valve with IPS grooved end connections and a globe-style body. It is designed to reduce high inlet pressures to a safe and stable outlet pressure, maintaining constant downstream pressure independent of flow rate. Constructed from ductile iron with stainless steel and Buna-N internals, it features internal and external epoxy coating for corrosion resistance. Standard components include isolation valves, pressure gauges, and a wye-type strainer for easy maintenance. Certified to ANSI/AWWA C530 and NSF/ANSI/CAN 61 lead-free standards, this valve ensures reliable performance in critical applications.

Additional Details

The Zurn Wilkins Model ZW209 is a 4 inch pilot-operated pressure reducing valve with IPS Grooved end connections and a Globe Style Body. It is designed for applications requiring the reduction of high inlet pressures to a safe and stable outlet pressure, maintaining constant downstream set pressure independent of flow rate.

Key Features

  • Epoxy coating applied internally and externally for enhanced corrosion protection
  • Includes a pilot assembly with a "Wye" Type Strainer, Isolation Valves, and Inlet and Outlet Pressure Gauges for quick and easy maintenance and repair
  • Pilot control is field adjustable from 15 psi to 120 psi, ensuring precise pressure regulation
  • Main valve features a stainless steel seat for durability and reliable sealing
  • This specific model is configured with a Reverse Pilot for an intended operating range of 50-165 PSI

Operation

  • The pilot assembly reacts to changes in downstream pressure, allowing the main valve to modulate and maintain a constant downstream set pressure.
  • The valve automatically seals shut once the downstream pressure reaches the pilot setting, preventing damage.
