Description

The Zurn Wilkins Model ZW209 is a 2.5-inch pilot-operated pressure reducing valve with grooved end connections, designed for fire suppression systems and other applications requiring stable downstream pressure. It features a ductile iron body with internal and external red epoxy coating for corrosion resistance. The pilot assembly ensures constant pressure regulation regardless of flow rate, automatically sealing shut to prevent damage. Standard components include isolation valves, pressure gauges, and a wye strainer for simplified maintenance. It meets ANSI/AWWA C530 and NSF/ANSI/CAN 61 lead-free standards. This valve maintains outlet pressure between 50-165 psi.

Additional Details

The 2-1/2 inch Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve with grooved end connections is designed for fire suppression systems and other applications requiring the reduction of high inlet pressures to safe and stable outlet pressures.

Features

  • The pilot assembly reacts to changes in downstream pressure allowing the main valve to modulate between closed and open, ensuring a constant downstream set pressure.
  • The valve automatically seals shut after reaching the pilot setting, preventing possible downstream damage.
  • Pressure regulation is not dependent upon flow rate, resulting in minimal pressure loss through the valve.
  • Internal and external ferrous surfaces are coated with a high-quality, red fusion epoxy coating for superior corrosion protection.
  • Standard components include isolation valves, inlet and outlet pressure gauges, and a "Wye" Type Strainer for quick and easy maintenance or repair.
  • The pilot control is field adjustable, maintaining outlet pressure between 50 psi and 165 psi.
  • Includes copper tubing and brass fittings for the pilot assembly.
