Typical Installation:

The upstream and downstream pressure gauges are required by Underwriters Laboratories® (UL). Also a relief valve of not less than 1/2" in size MUST be installed on the downstream side of the pressure control valve. Adequate drainage for the relief valve discharge must be provided.

Standards Compliance:

ANSI/AWWA C530; AWWA C606; ANSI B1.20.1; ANSI B16.42; NFPA 13; NFPA 14; NFPA 25

Features & Benefits:

• Pilot Operated Control: Maintains constant downstream pressure regardless of flow rate or inlet pressure variations.
• Corrosion Protection: Red epoxy coated internally and externally (FDA approved) for long-lasting durability.
• Installation Ready: Includes wye strainer, inlet/outlet pressure gauges with 3-way gauge isolation valves for quick setup.
• Adjustable Pressure Range: Field adjustable pilot spring from 50-165 psi residual pressure for versatile applications.

FAQ

Q: What is the adjustable pressure range for the Zurn 212-ZW209FPG?

A: The Wilkins 212-ZW209FPG pilot control is field adjustable from 50 psi to 165 psi residual pressure, with a maximum static pressure of 175 psi.

Q: Is a relief valve required when installing the Zurn 212-ZW209FPG?

A: Yes, UL installation requirements specify that a relief valve of not less than 1/2" in size MUST be installed on the downstream side of the pressure control valve with adequate drainage.

Q: What is the recommended installation orientation for this valve?

A: The recommended installation orientation is horizontal with the valve cover up. The 2 1/2" valve can be installed in other orientations, but proper air bleeding and maintenance access should be considered.
