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.
Eccentric Half Ball Valve Design & Industrial Applications
Learn how eccentric half-ball valves use an offset shaft and half-ball closure design to reduce seat rubbing, operating torque, and wear in abrasive, slurry, wastewater, pulp, ash, and solids-containing media. The guide explains the valve’s working principle, metal-seated sealing behavior, self-cleaning action, automation suitability, key selection factors, and differences from standard ball valves and butterfly valves in demanding industrial service.
