Connections

  • This Zurn Wilkins Model ZW209 valve features 3 inch Class 150 Flange end connections.
  • It is designed to connect to piping systems with compatible 3 inch Class 150 flanged connections.

Operation & Setup

The pilot control system is field adjustable, allowing the user to set the desired downstream pressure within a range of 15 psi to 120 psi. Ensure proper sizing and installation to achieve optimal pressure reduction and flow rates. Please note: The closing speed control (optional) on this valve should always be open at least three (3) turns off its seat.

Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed for many fire safety and industrial applications where the reduction of high inlet pressures to safe and stable outlet pressure is required. This 3-inch model features Class 150 flanged connections.

Operation and Performance

  • The pilot assembly reacts to changes in downstream pressure, allowing the main valve to modulate between closed and open positions to ensure a constant downstream set pressure.
  • Once the downstream pressure reaches the pilot setting, the main valve seals shut to prevent downstream damage.
  • Pressure regulation is not dependent upon flow rate, resulting in minimal pressure loss through the valve.

Corrosion Protection

  • Comes standard with epoxy coating internally and externally for superior corrosion protection.

Ease of Maintenance

  • Includes isolation valves and pressure gauges for quick and easy maintenance or repair.
  • The pilot control is field adjustable from 15 psi to 120 psi.
