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.
