Product Description

1 1/4" (31.75 mm) Threaded Butterfly Valve NPT with Tamper Switch offers precision flow control of gas, fluids and semi-solids. With a rated temperature of 32F (0C) to 176F (100C), this valve is suitable for indoor or outdoor use in water-based systems, including fire protection, at working pressures up to 175 PSI (12 BAR). Butterfly valves are often used in NFPA 13 and NFPA 14-compliant systems as control valves.

This 1 1/4" (31.75 mm) Threaded Butterfly Valve uses National Pipe Thread (NPT) for a leak-free seal upon installation. The polymer-coated ductile iron body and EPDM-rubber lined disc resist corrosion and mechanical damage. The handwheel assembly delivers a slow open and slow close, forming a leak-tight seal between the carbon-steel disc and NBR rubber O-ring.

A fitted tamper switch allows the 1 1/4" (31.75 mm) Threaded Butterfly Valve to activate a local alarm bell or horn when the valve comes to a partial or complete close. Dual supervisory switches and wiring make it easy to connect to a fire control panel.

UL listed and FM approved.
