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, ...

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 ...

• 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 ...

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 ...

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 ...

Proportional-integral-derivative (PID) is the most common industrial technology for closed-loop control. A proportional-integral-derivative (PID) controller can be used to control temperature, ...
