The VFOF-LE-BAH features a pneumatically controlled one-way flow control valve, non-return stop valves, and manual exhaust. Common applications for the valve are adjusting or stopping cylinder ...

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 ...

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 ...

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, ...

Ordinarily, if you want liquid to flow in only one direction through a pipe, that pipe needs to be equipped with a flap-type valve – which could fail. Now, however, scientists have created a new type ...

If you suddenly have the need for a two-way, flow control valve — from a valve-selection standpoint — what kind of questions do you ask yourself? Many, perhaps, don’t ask any questions and may make ...

Pneumatic control systems are used in various applications, including: A single acting cylinder (SAC) is a type of pneumatic actuator that produces force and movement in one direction only. It has a ...
