Commercial & Industrial Iron Butterfly Valves

Resilient-seated wafer & full-lug body styles are available in sizes 2" - 48". All iron butterfly valves have phenolic-reinforced liners & 416 SS blowout proof stems. Liner materials include EPDM, Buna-N, Viton*, Hypalon* and FDA Neoprene. Disc materials include aluminum bronze, DINP, 316 SS, epoxy & nylon coated. Operators include 10-position lever (locking standard), gear operators and stem extensions. All Milwaukee butterfly valves can be easily automated with pneumatic or electric actuators.
Actuated Butterfly Valves Works

A butterfly valve is a valve used for flow regulation in large pipe diameters in which the disc takes the form of disk. Operation is similar to that of a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.
