FLOW CONTROL

Home/Flow Control

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.
