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 ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However ...

To define control valve inherent flow characterization and inherent rangeability, and to recommend allowable deviations from characterizations curves which are described mathematically or graphically.

The Kettle Creek Flow Control Valve Design-Build project was developed to replace a single 30-in. plug valve and create a redundant flow train between two major potable water pipelines.
