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.
Pressure-compensated flow control valves are designed to provide a constant volume flow rate independent of the pressure drop across the valve. By contrast, non-pressure-compensated valves have a ...
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.
An in-line flow-control switch features both a female and a male luer lock. Consisting of a polycarbonate body and an acetal slider that acts as an on-off switch, the high-pressure 97337 switch can be ...
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 ...
The valve size and trim should match the required flow range, turndown ratio, and accuracy of the process. A mismatched valve can cause excessive noise, vibration, wear, leakage, or instability.
In this method, attributed to F.C. Yu, the control valve in a pumped application is assigned a minimum pressure drop at maximum design flow rate and maximum 80% control valve open position ...
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.
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 ...
