Description

The Zurn Wilkins Model ZW209 is a 4-inch pilot-operated pressure reducing valve designed for fire suppression systems. It ensures stable downstream pressure and accommodates high flow rates by modulating the main valve and sealing shut at the preset pilot point. Featuring a durable ductile iron globe body with grooved end connections, this valve is coated internally and externally with red epoxy for superior corrosion resistance. Standard components include isolation valves, inlet/outlet pressure gauges, and a "Wye" type strainer for simplified maintenance. It meets ANSI/AWWA C530 and NSF/ANSI/CAN 61 Lead Free standards, operating within a 33°F to 140°F temperature range. Item number 4-ZW209FPG.

Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed for fire suppression systems requiring stable downstream pressure from high inlet pressures and high flow rates.

This 4-inch valve features a pilot assembly that modulates the main valve to maintain constant downstream pressure, sealing shut once the pilot setting is reached to prevent potential damage downstream.

Construction & Features

  • Features grooved end connections for installation versatility.
  • Ductile iron main valve body and bonnet with stainless steel seat, disc guide, stem, and spring for durability.
  • Red epoxy coating applied internally and externally for enhanced corrosion resistance.
  • Standard equipped with isolation valves, inlet and outlet pressure gauges, and a "Wye" type strainer for easy maintenance and repair.
  • Includes copper tubing and brass fittings in the pilot assembly.
  • Pressure regulation is independent of flow rate, ensuring minimal pressure loss.

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