Anticavitation Control Choke Trim
The flow is directed through ports in an 'outer' flow cage and into a chamber inside the trim. It is then directed through ports in further flow cages until flow loses its high pressure and reaches the valve outlet. The tortuous routing of the flow uses energy and drops the fluid pressure in stages whilst the internal chambers allow for recovery.
VAC-CC trims are designed for specific process condition where cavitation is predicted to occur. Number of concentric cage used depends on pressure drop and number of stages required to ensure that cavitation eliminated.
