The difference maker

Operators have long faced challenges with minimum flow control, particle contamination, and poor rangeability, which can lead to valve clogging and require split range configurations. IMI’s EroSolve Metamorphic Trim is the solution to these problems. Our innovative trim can upgrade problematic valves to handle challenging operating conditions quickly and easily, with the option for custom designs to fit existing valve bodies and actuators, reducing installation costs.
