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 ...

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 ...

Some combined cycle plants have two feedwater-control valves: a small startup valve with the extra cavitation protection needed during startup and low-load operations, and a larger main valve with the ...

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 ...
