What are globe valves good for?
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.
What is the difference between globe valve and gate valve?
The main difference between globe and gate valve is in the form of the inner elements and the form of the flow inside the both valves . Globe valve has very good throttling ability while gate valve is not used for throttling.

Can globe valve be used for throttling?
A globe valve is most suitable for steam as the design of the valve allows for less wear on the seat compared to other types of valve. A globe valve’s design also allows for fine control and throttling.
How does a 3 way globe valve work?
A three-way ball valve has three ports or openings that are connected to piping or tubing for gas or fluid flow (media) to pass through. These ports are usually described as one inlet and two outlet ports or one outlet and two inlet ports depending upon the flow direction through the valve.
Is globe valve non return?
Uses: Globe valve is used in applications where variable pressure is required in the pipeline such as emergency bilge suction line etc. It can also be used as a non return valve. The type of valve where the disc is not attached to the spindle is called screw down non-return valve.
How many types of globe valves are available?
three
There are three basic globe valve body designs: Tee, Angle, and Wye.
Why globe valve is used in steam line?
Whereas most other valves would see the steam break through and tear it apart, globe valves offer greater resilience and could theoretically last for years in some applications. The type of valve most commonly compared alongside globe valves is gate valves. Both have the same purpose, to control the flow of media.
Can you install a globe valve backwards?
It is not recommended to install a globe valve upside down as it can cause dirt to accumulate in the bonnet. The preferred orientation of a globe valve is upright, however the valve may be installed in other directions, but any deviation from vertical is a compromise.
Does a globe valve have a rising stem?
Globe valves usually have rising stems, and the larger sizes are of the outside screw-and-yoke construction. Components of the Globe valve are similar to those of the gate valve. This type of valve has seats in a plane parallel or inclined to the line of flow.
