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 ...

Cavitation in hydraulic valves refers to the formation and rapid collapse of vapour cavities, which occurs when local pressure drops below the vapour pressure of the working fluid. This phenomenon can ...

This subcommittee will provide a forum in which to determine and evaluate the fundamental cavitation problems in control valve applications, to establish methods for evaluating the potential for ...

Control valves, particularly in heating systems, must be evaluated to determine the pressure required at the outlet to prevent cavitation. 3. Keep all points in the system above atmospheric pressure ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

3D printing techniques enable quieter, higher performing designs for final control elements. Control valve noise is a problem in many plant environments. The sound is created by very high pressure ...

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 ...
