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.
