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 ...

After all, the best value comes when a product enhances production and profitability. That is why ROSS is pleased to introduce customers to its two latest additions to the ROSS product family—the new ...

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, ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

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 ...

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 ...

• The first step in selecting a valve is determining its function. • Review Cv or pressure drop when considering one valve versus another. • Don’t overlook maintenance requirements when specifying a ...

Optimizing any cooling plant for minimal energy consumption is a demanding science. In many cases, minimizing chiller plant energy consumption requires modifications to the plant design, including ...

• Standard solenoid valves pose an ignition danger near hazardous materials. • Valves with pneumatic and magnetic actuators require no electricity, making them inherently safe in hazardous locations.
