Globe Valve

Globe valve, also known as a shut-off valve or stop valve, is a type of valve commonly used in pipelines. 


Globe valves are forced-seal valves that operate by relying on the disc to move through the seat channel to control the flow of fluid. Globe valves are typically used to cut off or regulate fluid flow, and are also suitable for throttling, with the following features:


1.Tightness. The sealing surface of the globe valve is usually flat or conical, and the disc moves in a straight line along the centerline of the valve seat to ensure good sealing performance.


Scope of application. These valves are suitable for a wide range of applications, including the control of different types of fluids such as air, water, steam, corrosive media, slurries, oils, liquid metals, and radioactive media.


2.Connection. The connection methods of globe valves include flange connection, thread connection and welded connection.


3.Fluid resistance. The fluid resistance of the globe valve is relatively large, and the opening and closing torque is also large, which may affect its application in some large-diameter occasions.


4.Opening and closing mode. The opening and closing of the globe valve usually moves the disc by rotating the handwheel, so as to achieve the passage or shut-off of the medium.


5.Flow. The medium flow direction of the globe valve is usually from above the disc into the valve cavity, which is designed to reduce the force during closing and improve the tightness.


6.Opening height. When the globe valve is opened, the opening height of the disc is 25% to 30% of the nominal diameter, and the flow rate has reached the maximum, indicating that the valve has reached the fully open position.


In addition, the shut-off valve is designed to be suitable for use in both low and medium pressure systems and high pressure systems. Get Price of globe valve manufacturer online!
