Additional Details

The Zurn Wilkins Model ZW209 is a pilot operated pressure reducing valve designed for fire protection and industrial applications where high inlet pressures need to be reduced to a safe and stable outlet pressure.

Its intelligent pilot assembly continuously modulates the main valve to ensure constant downstream pressure, automatically sealing shut to prevent damage once the desired set pressure is achieved.

Features

  • Pilot operated for stable downstream pressure, independent of flow rate.
  • Epoxy coated internally and externally for enhanced corrosion protection.
  • Includes standard isolation valves and inlet/outlet pressure gauges for quick and easy maintenance and repair.
  • Features a "Wye" Type Strainer and an Opening Speed Control (standard for 1 1/4 inch to 4 inch sizes).

Operation

  • The pilot valve senses downstream pressure fluctuations and adjusts the main valve to maintain consistent outlet pressure within narrow limits, regardless of changing flow rates or varying inlet pressures.

Corrosion Protection

  • All internal and external ferrous surfaces are coated with a high-quality, fusion epoxy coating, which is FDA approved, to ensure superior corrosion resistance.

Maintenance

  • Standard isolation valves and inlet/outlet pressure gauges simplify inspection and repair procedures.
  • The closing speed control (if present) for this valve should always be open at least three (3) turns off its seat to prevent damage or improper operation.

FAQs

What is the primary purpose of the Zurn Wilkins Model ZW209 valve?

The Zurn Wilkins Model ZW209 is a pilot operated pressure reducing valve designed to lower high inlet pressures to a safe and stable outlet pressure in fire protection and industrial systems, protecting downstream equipment.

What are the main materials used in the construction of this valve?

The main valve body and bonnet are constructed from ductile iron (ASTM A536). Key internal components like the disc guide, seat, stem, and spring are stainless steel, with a Buna-N rubber disc and nylon reinforced Buna-N diaphragm.

Is this pressure reducing valve suitable for potable water applications?

Yes, the Zurn Wilkins Model ZW209 meets the requirements of NSF/ANSI/CAN 61 for lead-free compliance, making it suitable for applications where lead content is a concern, including potable water.

What type of connections does the 212-ZW209FPTH model utilize?

The 212-ZW209FPTH model features 2.5 inch female NPT (FNPT) threaded connections on both the inlet and outlet, designed for compatibility with male NPT threaded pipes or fittings.

What maintenance features are included with the ZW209?

The ZW209 comes standard with isolation valves and inlet/outlet pressure gauges, which facilitate quick and easy maintenance and repair procedures. It also includes a "Wye" type strainer.
