Reducing Cavitation Damage in Control Valves
Here is a document that describes how cavitation occurs in control valves and what can be done to mitigate its adverse effects:
EBRO Resilient Seated Butterfly Valve Seat and Seal Replacement
The video below provides detailed, step-by-step training on replacing the seat and stem seals on an EBRO Armaturen "soft-seated" butterfly valve.
This style of valve is used for both on-off applications and as throttling control valves. Their design uses an "interference fit", meaning the metal disk is forced in contact with the soft rubber seat to provide a leak-tight seal. Because of this physical interaction, it is normal to replace the seats after a reasonable time in service.
