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 ...

Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

The valves can be customized to specific flow requirements. Each is available in 0.187 and 0.281 diameter models, allowing a designer to specify different metered flow rates for the forward and ...

Tens of thousands of valves are required to manage the myriad of fluid and gasses in a power generation facility. Whether the valve is for isolation, flow reversal protection or something completely ...

Many power plants use older control valve technologies that do not address the severe nature of today’s power plant operations. The older design valves require constant maintenance and their ...

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 ...

An oscillating control valve may appear to be the source of control instability and repair efforts are usually focused only there. When this fails to solve the issue, further investigation often ...

Directional-control valves are vital in any pneumatic circuit, directing or blocking airflow to control the speed or sequence of operations. One method of classifying directional-control valves is by ...
