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 valve internals or expose ...

Integrated slug-flow optimization can mitigate flow problems in a wide range of both offshore and onshore operating conditions. Slug flow is one of the most common flow states in horizontal and ...

We're always on the lookout for new stuff, so when information on Comp Cams dual conical valve springs came across our desk, we were eager to take a look. Comp introduced these dual conical springs in ...

Heavy oil (API gravity =22°) is dominated by high viscosity, asphaltene content, and temperature-sensitive rheology. These properties drive pressure losses, sand mobilization risk, emulsion formation, ...

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, ...

Gravel packing horizontal openhole laterals with washpipe diverter valves and external casing packers (ECPs) enables isolation of the produced oil stream from shale, water, gas, or other sections of ...

Like so many of the core technologies integral to automated industrial operations—such as motors, drives, and I/O—valves don’t always receive the attention they deserve in the automation arena.
