About Gear-Operated Lug Style Butterfly Valves

Install these valves on your flanged pipe system. They have threaded inserts on each side of the valve requiring two separate sets of bolts, allowing one side of pipe to be disconnected without affecting the other. They have a gear wheel for easy opening and closing.
