6 in. (152.4 mm) Wafer Butterfly Valve with Tamper Switch is designed to be seated between two pipe flanges for precision water flow control. With a rated temperature of 32F (0C) to 176F (80C), this valve is suitable for indoor or outdoor use in water-based systems, including as a control valve in fire protection systems.
This 6 in. (152.4 mm) Wafer Butterfly Valve has a working pressure of 300 PSI (20.7 BAR). 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 disc and NBR rubber O-ring.
A fitted tamper switch allows the 6 in. (152.4 mm) Wafer Butterfly Valve to activate a local alarm bell or horn when the valve comes to a partial or complete close. The bright-yellow position indicator offers an at-a-glance indication of the valve's position.
Dual supervisory switches and wiring make it easy to connect the 6 in. (152.4 mm) Wafer Butterfly Valve to a fire control panel. Designed to install quickly with a roll-grooved body. When closed, this valve allows for immediate replacement of the down-flow end of the pipe, eliminating the need to drain the entire system during repairs or improvements.
UL-listed and FM-approved.
