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.
Soft Seat vs Metal Seat Ball Valve Explained
Compare soft-seated and metal-seated ball valves by sealing performance, temperature capability, media compatibility, operating torque, service life, and cost. Soft seats such as PTFE, RPTFE, and PEEK provide bubble-tight shutoff and low torque for clean, moderate-temperature fluids, while metal seats with hardened coatings are better suited to high-temperature, abrasive, corrosive, fire-safe, and severe-service applications.
