CavControl valve trim lowers cavitation damage by controlling the location and concentration of cavitation vapor bubble implosions in an area away from metal parts. CavControl trim utilizes a number of small, diametrically opposed flow holes through the walls of a special seat retainer.

Features & Benefits
- Tolerates Sigma as low as 1.2
- Uses a drilled hole seat retainer with stepped holes to move the vena contracta away from metal surfaces
- Controls cavitation by directing the cavitation bubbles away from the metal surfaces and into opposing streams from the opposite side of the retainer
- Impinging jets create a column of cavitation in the center of the retainer
- Works best in low to mild cavitation
