MicroCav Anti-Cavitation Control Valve Trim

MicroCav trim is used to effectively handle cavitation in Valtek control valves that require small flow rates (maximum CV values from 1.25 to 0.007).To effectively prevent cavitation damage, the preferred application is with an angle-style valve body with hardened trim. A slightly modified design can also be used on a limited basis for globe valve applications.

The MicroCav design utilizes a special plug that is closely guided within the seat ring. The plug head is designed with a series of special-engineered grooves that continually expand as they progress diagonally along the length and around the circumference of the plug head allowing the grooves to continually intersect with each other. The fluid passes through the grooves, experiencing a continual increase in flow area while allowing for staged pressure reduction. Staged pressure reduction takes place as the fluid impinges upon itself when the grooves intersect.
