Additional Details

The Zurn Wilkins Model ZW209 Pressure Reducing Valve is a pilot-operated valve designed for fire suppression systems where a steady downstream pressure and high flow rates are essential.

Its pilot assembly precisely modulates the main valve between open and closed positions to maintain constant downstream pressure, automatically sealing shut once the set pressure is reached to prevent system damage.

Application

  • Designed for fire suppression systems requiring stable outlet pressure and high flow rates.
  • Reduces high inlet pressures to safe and stable outlet pressures.

Standard Features

  • Epoxy coated internally and externally for corrosion protection.
  • Includes isolation valves and pressure gauges for simplified maintenance and repair.
  • Pilot assembly reacts to downstream pressure changes, modulating the main valve for constant pressure.
  • "Wye" Type Strainer included.
  • Copper Tubing and Brass Fittings.
