Typical Installation:

The upstream and downstream pressure gauges are required by Underwriters Laboratories (UL). A relief valve of not less than 1/2 Inch in size must be installed on the downstream side of the pressure control valve. Adequate drainage for the relief valve discharge must be provided. The valve is to be installed in accordance with NFPA 13 for sprinkler systems or NFPA 14 for standpipes and hose systems, and inspected, tested and maintained per NFPA 25. The recommended installation orientation is horizontal with the valve cover up; 6 Inch and larger valves should only be installed horizontally due to maintenance and air bleeding requirements.

Standards Compliance:

ANSI/AWWA C530; AWWA C606; ANSI B1.20.1; UL Listed; C-UL Listed; NFPA 13; NFPA 14; NFPA 25

Features & Benefits:

• Pilot Operated Control: Modulates to maintain constant downstream pressure regardless of flow rate or inlet pressure variations, ensuring stable fire protection performance.
• Corrosion Protection: Red epoxy coating (FDA approved) on all internal and external ferrous surfaces provides long-lasting durability in fire suppression environments.
• Complete Installation Package: Includes wye strainer, inlet and outlet pressure gauges with 3-way isolation valves for quick installation, adjustment, and maintenance.
• Field Adjustable Pilot: Adjustable spring range from 50 to 165 psi allows precise downstream pressure control to meet specific fire protection system requirements.
