Advances in control valve trim manufacturing are set to alleviate cavitation issues that are costing process and industrial plants thousands of pounds’ maintenance, repair and operational (MRO) spend.

To prevent or reduce cavitation, some control valves use a venturi-shaped trim, which is a tapered section that creates a smooth pressure recovery and reduces the velocity of the fluid.
