Description

The Zurn Wilkins Model ZW209 is a 1.5 inch pilot-operated pressure reducing valve designed for fire protection systems requiring stable downstream pressure. It features a robust ductile iron body with internal and external epoxy coating for superior corrosion resistance and FDA Approved assembly. Standard components like isolation valves, pressure gauges, and a wye strainer ensure easy maintenance. The valve modulates to maintain constant outlet pressure, automatically sealing shut to prevent downstream damage. It is certified to NSF/ANSI/CAN 61 and ANSI/AWWA C530, ideal for applications needing reliable pressure control with 400 PSI rating and FNPT threaded connections. Item number 112-ZW209FPTH.

Connections

  • The 1.5 inch Zurn Wilkins Model ZW209 Pressure Reducing Valve connects to the piping system using Female NPT (FNPT) threaded connections on both the inlet and outlet.
  • Ensure that the mating male NPT threads on your piping system are also 1.5 inches for proper compatibility and a secure seal.

Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed for fire suppression systems, ensuring the reduction of high inlet pressures to safe and stable outlet pressures.

The pilot assembly reacts to changes in downstream pressure, allowing the main valve to modulate between closed and open positions to maintain a constant downstream set pressure. Once the pilot setting is reached, the main valve seals shut to prevent downstream damage.

Features

  • Main valve is epoxy coated internally and externally for enhanced corrosion protection, compliant with FDA Approved assembly.
  • Includes a pilot assembly with a "Wye" Type Strainer, Opening Speed Control (for sizes 1 1/4" - 4"), and isolation valves.
  • Equipped with inlet and outlet pressure gauges for quick and easy maintenance and repair.
  • Pressure regulation is not dependent upon flow rate, ensuring minimal pressure loss through the valve.
  • Designed for constant downstream pressure and high flow rates in fire suppression applications.

Materials

  • Main Valve Body: Ductile Iron ASTM A536
