What Is a Globe Valve?
A globe valve is a type of control valve designed to start, stop, or modulate the flow of media through a pipeline. It gets its name from the spherical body shape used in early designs, although modern versions can vary in appearance.
What makes globe valves unique is their linear motion operation. The internal disc (or plug) moves up and down inside the valve body to allow, restrict, or block flow. This mechanism allows for accurate throttling, making globe valves ideal when flow regulation is essential.
How Does a Globe Valve Work?
Globe valves consist of a few core components:
Valve Body: The main housing where fluid enters and exits
Disc or Plug: Moves to open or close the valve
Seat: Provides a sealing surface for the disc
Stem: Connects the disc to a handwheel or actuator
When the handwheel or actuator is operated, the stem moves vertically. This movement controls the disc’s position inside the valve:
Open: The disc lifts from the seat, allowing full flow
Partially Open: The disc throttles flow to the desired level
Closed: The disc seals tightly against the seat to block flow
The globe valve’s design causes the fluid to change direction, which increases pressure drop but allows for highly accurate flow control. This makes it an excellent choice for systems that require steady, modulated flow such as steam, heating, or processing lines.
Common Applications
Globe valves are used across many industries, including:
They are available with flanged, threaded, or welded ends to suit various pipework configurations and pressure ratings.
