Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is engineered to reduce high inlet pressures to a safe and stable outlet pressure in demanding applications. Its pilot assembly reacts dynamically to downstream pressure changes, modulating the main valve to ensure a constant set pressure.

Key Features

  • Pilot assembly dynamically reacts to downstream pressure changes, ensuring stable downstream pressure.
  • Main valve modulates between closed and open positions to maintain a constant set pressure, sealing shut after reaching pilot setting to prevent downstream damage.
  • Internal and external epoxy coating provides superior corrosion protection and is FDA approved.
  • Standard components include isolation valves and pressure gauges for quick and easy maintenance.
  • Features a "Wye" Type Strainer for system protection.
