Connections

This Zurn Wilkins ZW209 valve features 10 inch IPS Grooved end connections for installation. Its angle body design directs flow through a 90-degree turn. The pilot valve assembly is designed to install on the discharge side of the control circuitry.

Installation Note

  • For valves 6 inches and larger, including this 10-inch model, the recommended installation orientation is horizontal with the valve cover up. This helps ensure proper air bleeding from the cover and facilitates maintenance.

Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed to reduce high inlet pressures to safe and stable outlet pressure in a wide range of applications, maintaining constant downstream pressure regardless of flow rate changes. This 10-inch valve features an angle body with IPS grooved connections.

Reliable Performance

  • The pilot assembly reacts to changes in downstream pressure, allowing the main valve to modulate and maintain a constant set pressure.
  • The main valve seals shut when the downstream pressure reaches the pilot setting, preventing damage.
  • Pressure regulation is not dependent upon flow rate, ensuring minimal pressure loss.

Construction & Durability

  • Epoxy coating, internally and externally, provides superior corrosion protection and is FDA approved.
  • Main valve body and bonnet are constructed from Ductile Iron ASTM A536.
  • Disc guide, seat, stem, and spring are made of Stainless Steel.
  • Disc is Buna-N Rubber and diaphragm is Nylon Reinforced Buna-N.

Ease of Maintenance

  • Comes standard with isolation valves and pressure gauges for quick and easy maintenance or repair.
  • Standard pilot assembly includes a "Wye" type strainer and copper tubing with brass fittings.

Safety & Compliance

  • Meets ANSI/AWWA C530 and NSF/ANSI/CAN 61 requirements, certified lead-free with a maximum 0.25% weighted average lead content.

The optional closing speed control (not included with this specific configuration) should always be open at least three (3) turns off its seat.
