Valve Material Selection Guide: Body, Trim, Seat and Seal Materials
Learn how to choose valve materials by body, trim, seat, seal, medium, pressure, temperature, corrosion risk, and industrial application requirements.
PTFE vs PEEK: Choosing the Right Ball Valve Seal
Compare PTFE and PEEK ball valve seats by chemical resistance, temperature capability, pressure resistance, wear performance, operating torque, and cost. PTFE seats are economical and highly resistant to aggressive chemicals in moderate-temperature service, while PEEK seats provide greater mechanical strength, dimensional stability, and durability for high-pressure, high-temperature, and severe industrial applications.
