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

Features & Benefits
- Tolerates Sigma as low as 1.2
- Uses the same technology as CavControl to control cavitation, except the holes are drilled into a special close-guided plug head rather than in the seat retainer
- Impinging jets create a column of cavitation in the center of the plug head, keeping the bubbles away from metal surfaces
- Same performance as CavControl with much lower capacities
- Flow characteristics of trim can be modified through porting size
