What are the classifications of industrial-grade valves?

Industrial-grade valves refer to all kinds of valves that are widely used in the industrial field, which are used to control the flow of fluids, and have the characteristics of solid structure, reliable performance and long life. Depending on the use and principle of operation, industrial-grade valves can be divided into the following categories:

 

Globe valve: Mainly used to cut off or turn on the flow of media, its structure is characterized by a movable disc that controls the opening and closing of the disc by rotating the valve stem.

 

Gate valves: They are also used to cut off or turn on the flow of media, but their working principle is to change the flow area by lifting or lowering the disc, and are often used in large diameter pipes.

 

Control valve: It is used to regulate the pressure, flow and direction of the fluid, and the control of the fluid parameters is achieved by changing the flow area in the valve.

 

Valve: Used to protect the operation of the piping system, when the pressure exceeds the set value, it automatically opens and discharges excess pressure to avoid pipeline rupture.

 

Diaphragm valves: Controls the flow of fluids by compressing or stretching the diaphragm and is suitable for corrosive media and fluids containing solid particles.

 

Plug Valve: Rotates the stem to drive the to rotate to control the opening and closing of the fluid, compact and suitable for small flow and high viscosity fluids.

 

Ball Valve: There is a spherical shut-off element inside, which controls the flow of fluid by rotating the ball, with good sealing performance and small flow resistance.

 

Butterfly valve: The opening and closing of the fluid is controlled by rotating the butterfly plate on the shaft, which is simple in structure and easy to operate, and is often used for ventilation and flow regulation.

 

Check Valve: Automatically prevents the medium from backflowing, only allows the medium to flow in one direction, and its structure is characterized by a movable disc that automatically closes when the medium flows backwards.

When selecting an industrial-grade valve, it is necessary to consider factors such as the nature of the medium, flow requirements, working environment (e.g., temperature, pressure, vibration, etc.), installation space, maintenance costs, and budget.
