As their name suggests, globe valves are linear motion valves with
rounded globular shaped bodies. Since their shape is similar to
other valve bodies, positive identification must be made based on
internal piping. Recently globe Globe Valve image valves have lost
their traditional round body-shape. Globe valves have many
advantages and disadvantages for users.
They have excellent and precise throttling ability for
high-pressure systems. The disadvantages include low-flow
coefficients and a longer operating time because the operator must
turn the handle and stem many times to ensure the valve is
completely open or completely closed. Globe valves can be used in
systems that require frequent stroking, vacuum, and systems that
have a wide range of temperature extremes.
The globe valve is used for throttling flow control. Shut off is
accomplished by moving the disc against the flow stream rather than
across it as in the case with a gate valve. The flow pattern
through a globe valve involves changes in direction, resulting in
greater resistance to flow, causing high pressure drop. The globe
valve is an excellent valve to use for on-off service, but is
highly suited for frequent cycling and control of fluids anywhere
in amount or volume between the open and closed positions.
The globe valve must be installed in the proper relation to the
media flow as indicated by the flow direction arrow marked on the
valve body. This valve is considered uni-directional and must be
installed with the pressure side or inlet under the seat.
We provide globe Valves are manufactured as full port, with
threaded, socket-weld, flanged and butt weld ends.
Pressure classes include 150 through 1500.
