Body Configuration

  • This Zurn Wilkins ZW209 valve features an Angle Style Body, which is often chosen for installations where a compact footprint is needed or to change the direction of piping immediately after the valve.

Connections

  • The valve is equipped with IPS Grooved connections, designed for use with grooved pipe couplings. This type of connection allows for efficient and secure assembly, typically simplifying installation and maintenance procedures compared to threaded or flanged connections for this size.

Pilot System Components

  • The integrated pilot assembly includes copper tubing and brass fittings, which are standard for the control circuitry.

Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed for applications requiring the reduction of high inlet pressures to a safe and stable outlet pressure. It ensures a constant downstream set pressure by modulating between closed and open positions.

This model features an angle style body and IPS grooved connections, making it suitable for various industrial and fire-safety installations.

Key Features

  • Pilot Operated Design: The pilot assembly reacts to downstream pressure changes, modulating the main valve for constant outlet pressure.
  • Corrosion Protection: Epoxy coating on all internal and external ferrous surfaces ensures durability and extended lifespan.
  • Ease of Maintenance: Comes standard with isolation valves and inlet/outlet pressure gauges for quick and easy servicing.
  • Main Valve Body: Constructed from Ductile Iron ASTM A536 for robust performance.
  • Pilot System Components: Includes a "Wye" Type Strainer, Opening Speed Control (for sizes 1 1/4" - 4"), Isolation Valves, Inlet and Outlet Pressure Gauges, ANSI Class 150 Flanges, Copper Tubing, and Brass Fittings.
  • NSF/ANSI/CAN 61 Certified: Meets requirements for lead content, suitable for potable water applications.

The closing speed control (optional) on this valve should always be open at least three (3) turns off its seat to prevent potential issues.
