McWane - Seat-On-Disc Butterfly Valve - Brochure

Designed for years of dependable service, the superior design of our butterfly valve provides ease of adjustment along with the ensured dependability expected in any distribution system or plant installation. Our butterfly valve has a 100% bubble tight seal via a 316 stainless steel ring located in the body, and rubber seat located on the vane. The rubber seat provides a `zero leakage` alternative to metal-seated valves. For pump station and treatment plant applications, butterfly valves offer flow control advantages (such as throttling) over gate valves,and are much more economical. Our butterfly valves are manufactured in accordance with the American Water Works Association (AWWA) C504 standard. Butterfly valves are constructed of ductile iron, stainless steel, rubber seats & seals. The strength of ductile iron along with stainless steel components provide corrosion resistance for buried service applications.
