Connections & Installation

  • This valve features a 2.5 inch Class 300 Flange end connection.
  • The ZW209 is designed with a Globe Style Body configuration.
  • For proper operation and maintenance, the recommended installation orientation for Automatic Control Valves (ACVs) is horizontal with the valve cover up. While this valve is 2.5 inches, larger valves (6 inches and up) particularly benefit from this orientation to ensure proper air bleeding and serviceability.
  • The pilot assembly controls the main valve's modulation by reacting to downstream pressure changes, ensuring a stable outlet pressure.

Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed to reduce high inlet pressures to a safe and stable outlet pressure in fire-safety and industrial applications.

This valve maintains a constant downstream set pressure by modulating between closed and open positions, preventing downstream damage by automatically sealing shut once the pilot setting is reached.

Features

  • Provides constant downstream set pressure regardless of flow rate.
  • Epoxy coating, internally and externally, offers superior corrosion protection.
  • Includes isolation valves and pressure gauges for simplified maintenance and repair.
  • Equipped with a "Wye" Type Strainer for system protection.
  • Features an Opening Speed Control, applicable for sizes 1 1/4" - 4".

Warning: For valves with opening speed control (sizes 1 1/4" - 4"), the control should always be open at least three (3) turns off its seat.
