How to avoid cavitation and flashing in valves, and what to do if such phenomena occur.
If cavitation and flashing occur, the bursting of the bubbles generated exerts intense force on the valve body and other components, damaging the valve
A multi-stage pressure reduction control valve can be used.
I agree with the view above: cavitation and flashing not only cause damage to the valve core and seat but also to the valve body itself. In simple terms: 1. Avoid operating the control valve at low opening degrees, and increase the surface hardness of the valve core and seat. 2. Special valve internals can be used to prevent this, such as multi-stage pressure reduction mechanisms and labyrinth designs. 3. If these methods don’t work, use a corner valve.
Cage valves can be used to eliminate the above two issues
