Valves are essential elements for controlling fluid system performance. Virtually every fluid-power system requires some type of valve. In a hydraulic system, valves may control pressure, flow to an ...

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, ...

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 ...

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.

Electronically controlled electric valves have been accepted for years in larger applications, just as chillers have been, and have proven to add efficiency to the systems. The key to the increase in ...

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 ...

Phoenix Controls helps safely and efficiently manage sterile airflow control and room pressure in clean rooms with its ...
