CAVFLO Cavitation Service Valves

CAVFLO trim is used in liquid applications to protect control valves from cavitation damage. The CAVFLO trim controls where the cavitation vapor bubbles collapse keeping them away from valve components. It works by reducing the flow into many small flow streams through the carefully engineered holes in the CAVFLO trim.

The design of these holes ensures the vena contracts and the formation of cavitation vapor bubbles occurs as the flow exits the retainer. The flow streams are directed into the centre of the trim, where opposing streams collide allowing the cavitation vapor bubbles to collapse harmlessly against themselves, away from valve components.

CAVFLO trim fits standard GFLO bodies and can be supplied with =%, linear or bi-linear flow characteristics.
