Additional Details

The 3 inch Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed for critical applications requiring stable downstream pressure from high inlet pressures, such as in Fire Suppression Systems.

This valve features a reactive pilot assembly that modulates the main valve to maintain constant downstream set pressure, automatically sealing shut to prevent damage once the pilot setting is reached. The internal and external red epoxy coating provides excellent corrosion resistance, ensuring durability and longevity.

Features

  • Pilot-operated design ensures stable downstream pressure regulation regardless of flow rate changes.
  • Equipped with isolation valves and pressure gauges for simplified maintenance and repair.
  • Red epoxy coating applied internally and externally for superior corrosion protection.
  • Main valve modulates between closed and open positions to maintain consistent pressure.
  • Pilot assembly reacts to changes in downstream pressure, sealing shut to prevent damage.
  • Designed for minimal pressure loss through the valve.

Construction

  • Main Valve Body: Ductile Iron ASTM A536
  • Main Valve Bonnet: Ductile Iron ASTM A536
  • Seat: Stainless Steel
  • Disc: Buna-N Rubber
  • Diaphragm: Nylon Reinforced Buna-N
  • Stem: Stainless Steel
The closing speed control (optional) on this valve should always be open at least three (3) turns off its seat.
