Valve Construction

• GLOBE BODIES are Sand Cast Bronze – Max Pressure Rated: WSP 200 psi – WOG 400 psi.
• BONNET ASSEMBLIES are 304 SS Tubes with Brass Tube Plugs Silver–soldered to a Brass Bonnet. BONNET O–RING is Viton®.
• PISTON ASSEMBLIES are Brass or Bronze with Brass SEAT SCREWS and a Teflon® Insert. 316SS EXPANDER RINGS are behind Glass & Moly–Filled Teflon® PISTON RINGS plus a Teflon® SEAT DISC and Brass or Bronze GUIDE NUT.
• PILOT VALVE is 416SS and PISTON SPRING is 302SS.

MOUNTING & SERVICE

• Installation: Valves must be mounted in horizontal pipe with coil vertical, upright and on top. A 40–mesh inline strainer is recommended ahead of the valve. Valve will not open on a Closed System (equalizes pressure across the valve).
• Maintenance: As with any piece of equipment, reasonable inspection and maintenance of components should be periodically performed. Frequently check operation, cleanliness and internal wear. Any questions, consult factory.

NOTE: Gould Solenoid Valves are designed for Industrial–Commercial applications. Residential/Consumer applications will void the warranty. Questions ~ Call our Experts.
