Lines around the plant need flow that can be finely controlled or shut off. Globe valves do that by lifting a disc onto a seat.
By how far the disc is lifted, the valve throttles the flow, and pressed onto the seat it shuts the flow off.
This guide explains what globe valves do, where they fit, and how to keep them reliable.
What Globe Valves Do
In a globe valve a disc lifts onto or away from a seat as the stem is turned, which opens, throttles, or shuts the flow.
Because the disc can be set at any lift, the valve throttles the flow finely, not just fully open or shut.
Pressed firmly onto the seat, the disc shuts the flow off tightly.
Where They Fit in the Plant
Lines carrying juice, water, and other liquids that need fine flow control or a tight shut off suit globe valves.
Wherever a flow must be throttled to the right rate or stopped cleanly, a globe valve does it.
By controlling the flow, the valves let each part of the process get the flow it needs.
Signs the Valve Needs Attention
A valve in trouble shows up in the flow and the seal.
- The valve passing when it should be shut
- The flow not controlled as it should be
- Leaks at the seat or the stem
- Wear on the seat from the liquid
- The valve hard to open or close
What Makes a Good Valve?
A valve is judged by a tight seal and reliable control.
Fine Flow Control
The disc must throttle the flow finely at any lift. Fine control is what suits the globe valve to careful duties.
A Tight Shut Off
Pressed onto the seat, the disc must shut the flow tight. A tight shut off is what stops the flow cleanly.
Keeping the Valve Working
Routine attention keeps the valve controlling your flow.
- Watch that the valve seals tight when shut
- Watch that it controls the flow well
- Check the seat and stem for leaks and wear
- Keep the valve free to open and close
Common Questions About Globe Valves
Globe valves throttle and shut off the flow in a line by lifting a disc onto a seat, so flow can be finely controlled or stopped where the plant needs it.
Lines carrying juice, water, and other liquids that need fine flow control or a tight shut off suit globe valves.
A valve that does not seal tight passes flow when it should be shut, which loses control of the process and wastes what it should hold back.
Watching that it seals tight and controls the flow, checking the seat and stem for leaks and wear, and keeping it free to move keep the valve working.
Control the Flow Reliably
A globe valvegives tight, reliable control of the flow where the plant needs it. A tight seal and reliable control are what make it dependable.
