Butterfly Valves

Butterfly valves are used for throttling, regulating flow volumes and full on, full off control.   Best suited for applications having to do with isolation and control of liquids, gases or slurries, the valve disc is located inside the valve body, and pivots 90 degrees around the stem to regulate the flow.  Butterfly valves are lightweight and easy to mount.

We can provide cast & forged butterfly valves in the following materials: 304L, CF3, 304 SS, CF8, 316 SS, CF8M, 317L, CG8M,  321 SS, 347 SS, CF8C, F5, F9, F11, F 22, F91, DUPLEX 2205, MONEL, ALLOY 20, CN7M,  HASTELLOY C, CW12MW, HAST C-22,  410 SS, INCONEL 600, INCONEL 625, INCOLLOY 800.
