Restrictive flow regulators work like an automatic variable orifice to control flow by throttling or restricting. Compensator spool movement blocks fluid flow through the valve.

1. Flow-to-open cutaway. Control valves equipped with noise-abatement trim, such as a drilled-hole cage or a tortuous path stack, are typically oriented in the flow-to-open direction.

Valve rangeability is often stated as simply a deviation of the catalog flow characteristic from the theoretical characteristic. Here we will see how the consideration of the changes in process ...

Choked Flow in Control Valves Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage ...

F low control valves control the movement or pressure of fluid. A valve is basically a mechanical device that blocks a tube or pipe either partially or completely to change the amount of fluid that ...

Figure 1 is an example of a control-valve sizing datasheet that indicates flashing but not choked flow. There is a note stating that the valve will be in flashing conditions. The software that created ...
