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 ...

Inherent control valve flow characteristics are established assuming a constant Δp across the valve. If the valve Δp is reduced as the flow increases, meaning that there is a valve pressure drop decay ...

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.
