CONTROL SYSTEMS

Valves are mechanical elements that regulate and control liquid or gas flow.

Valves control flow rate or pressure by changing flow passage area.

​

There are many types. For example:

• Globe valves

• Gate valves

• Piston valves

• Membrane valves

• Spherical valves

• Plug valves

• Butterfly valves

• Check valves

• Control valves

• Balance valves

• etc.

 

Some of the information that valve designers and manufacturers can obtain from CFD analysis include:

 

• Flow pattern in the valve

• Flow rate through the valve

• Pressure drop in the valve

• Discharge coefficient

• Pressure loss coefficient

• Forces acting on the disc

• Moments acting on the disc

• Cavitation

• Erosion

• etc.
