GLOBE VALVE

Globe Valves are all characterised by a closer member, usually in
disc or plug form, which is moved by the actuator perpendicular to
a ring shaped seat. The flow passes from the inlet port through
the seat to outlet port. The types differ mainly in the orientation of
the seat to the direction of flow through the valve.

Globe valves are used primarily for throttling purpose. They are
widely used along with gate valves in power and process piping
system. Globe valves may be considered a general purpose flow
control valves.

Globe valves are generally faster to open or close then the gate
valve. Their seating surfaces are less subject to wear and their
high pressure drop makes them useful in controlling pressure.

Their high pressure drop may be undesirable in many piping
systems. In large size they require considerable power to operate,
thus necessitating gearing, levers etc. Globe valves are often
heavier than other valves of the same flow rating.
