Cavitation-Control Technologies
utilizes a cavitation-control mechanism consisting
of special flow paths to prevent impingement on
critical trim components.
Micro-Flat trim is intended for low-flow applications
in the flow-down direction only. The trim design
does not eliminate cavitation but controls where it
occurs to minimize damage.
Micro-Flat trim features a protected seat design to
maximize seat life in cavitating environments.
The trim is available in hardened materials only,
such as R30006/CoCr-A and S44004. These
materials are needed to provide wear resistance
between the plug and seat ring. An outlet liner is
provided to protect the valve body.
Micro-Flat cavitation trim is recommended for
angle valve applications. In special cases, it can be
engineered into a globe valve body.
