Globe valve

Globe valve

The globe valve, also known as the shut-off valve, is a forced-sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the force of the stem and the head friction of the filler and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve. , So the diameter of the valve stem should be large, otherwise the valve stem will bend failure.

Best globe valve

A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body.

The opening and closing part of the globe valve is a plug-shaped valve disc, and the sealing surface is flat or conical. The valve disc moves linearly along the center line of the valve seat. The movement form of the valve stem, (common name: dark stem), also has a lifting and rotating rod type, which can be used to control various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. flow. Therefore, this type of shut-off valve is very suitable for shutting off or regulating and throttling.

Frequently Asked Question

Do you have any question?

Globe valves, so-called because of their outside shape, are widely used in plant piping. They are suitable for manual and automatic operation. Unlike the gate valve, globe valve can be used for regulating flow or pressures as well as complete shutoff of flow.

Gate valves are used for On-Off control while Globe valves are used for flow regulation. Gate valves offer little resistance to fluid flow in fully open position and also have small pressure drop across the valve. Is that correct? The globe valves are not.

The main difference between these two types is the way they close. A globe valve uses a plug (stem) that closes against the flow, and a ball valve has a gate (ball) that closes across the flow. Globe valves are good for regulating flow, whereas ball valves are better for on/off control without pressure drop.
