Butterfly Valve

Butterfly Valve

Butterfly Valve is one of the most compact and light-weight valves. Used for a wide range of applications, the choice of seat, lining and disc options has increased significantly over recent years making the valve a popular choice. A wide range of materials, sizes and pressure ratings gives reliable positive isolation and moderate flow control capability over a wide range of applications throughout the industry. The metal seated valve is well established in petrochemical and oil industries being lightweight, fire safe and suitable for actuation.Butterfly valves offer a number of advantages when used for the proper application. They may be used in a wide variety of chemical services, they are available with small dimensions allowing for use in areas where space is limited, and they allow a high coefficient of flow.

Butterfly valves are quick opening valves that consist of a metal circular disc or vane with its pivot axes at right angles to the direction of flow in the pipe, which when rotated on a shaft, seals against seats in thevalve body. They are normally used as throttling valves to control flow. Unlike ball valves, butterfly valves do not
