It takes a large number of control valves to run a power plant, and while some valves are more critical to plant operations than others, it always follows that when a severe service valve fails, the ...

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 ...

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, ...

• 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 ...

On/off valves are basically on/off switches for hydraulic systems. They are typically installed in applications where precise position or speed control is not required. Proportional valves adjust flow ...

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.

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.
