Deep machined pockets protect the seat and minimizes the chance of media and pressure liftting the seat causing damage. Materials include PTFE, RPTFE, C-RPTFE, UHMWPE, KEL-F, and others upon request Note: A material's tendency to compress or move under load may limit their use at higher pressures and temperatures.
