Butterfly Valves

The butterfly valve is one of the smallest and lightest valves available. The valve is widely used for a variety of applications, and the number of seat, lining, and disc alternatives has grown dramatically in recent years, making it a popular choice. A diverse choice of materials, sizes, and pressure ratings ensures reliable positive isolation and moderate flow control in a variety of applications across the industry. The metal seated valve is well-known in the petrochemical and oil industries for being lightweight, fire-resistant, and actuation-ready. When utilised correctly, butterfly valves provide a variety of benefits.

Butterfly valves are quick-opening valves that consist of a metal circular disc or vane with pivot axes at right angles to the pipe’s flow direction, which seals against seats in the valve body when rotated on a shaft. They’re typically used to control flow as throttling valves. Butterfly valves, unlike ball valves, don’t have any pockets where fluids could become trapped when the valve is closed.
