Gear-Operated Butterfly Valve

A butterfly valve with gear linkage used to isolate a column or section in a fire line; since it does not require a flange kit, it saves space in tight installation areas. In the monitored key model, valve closure is reported to the fire panel, thus preventing the line from being left closed without awareness. The seal is selected as EPDM or NBR, the body is epoxy coated; operation is provided with lever or gear-reduced actuators.
