Common noncompensated valves are adjustable needle valves; flow through them varies with fluid viscosity and pressure across the valve. Usually, a needle valve is paired with a check valve that ...

August 2021 Choked Flow in Control Valves Choked Flow in Control Valves By Katherine Bartels, Adam Harmon Summary Choked flow in control valves is a subject of serious concern for industrial users.

UK-based flow control equipment specialist Oxford has begun commercial trials of its stemless control valve with the Abu ...

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.

Valves play a critical role in the spacecraft’s architecture, regulating the flow of pressurents, like helium, and propellants.

Note that the difference between the boiler feed pump head-flow curve and the system resistance curve (Figure 1) provides the basis for the pressure drop available for the drum level control valve.
