Stainless Steel Butterfly Valves
Stainless steel butterfly valves are devices that regulate the flow of various liquids and gases in pipes. Butterfly valves are rotary valves, meaning their disc rotates a quarter turn between the open and closed positions. Like all butterfly valves, stainless steel butterfly valves consist of a seal around a pipe wall, a round disc or plate, and a control lever.
The body and disc of stainless steel butterfly valves are made of stainless steel materials. Stainless steel is a metal that is resistant to corrosion and oxidation. It is chosen over other metals and traditional steel because it has a longer life and requires less maintenance. Stainless steel is also highly sanitary and easy to clean.
Operators of stainless steel butterfly valves can control the flow of a fluid or gas by pulling a lever that opens or closes the valve. When the disc is parallel to the flow of water, the valve is in open position and lets all gases or liquids pass; when the handle is turned, the disc rotates around to a position parallel to the flow of water. It fits snugly into the seal and blocks all flow through the pipe.
Stainless steel butterfly valves are an efficient and reasonably inexpensive type of flow control device. They are used in water distribution, chemical services, and in ventilation applications.
