One of the most compact and light-weight valves
available. 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, firesafe
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 the valve body. They are
normally used as throttling valves to control flow. Unlike
ball valves, butterfly valves do not have any pockets
in which fluids may become trapped when the valve is closed.
