The main difference between double eccentric butterfly valves and soft sealing butterfly valves lies in their sealing mechanisms. Double eccentric valves achieve sealing through metal-to-metal contact between the disc and the seat.
Pressure and Temperature Ratings:
Double eccentric butterfly valves are designed to handle higher pressures and temperatures compared to soft sealing butterfly valves.
Double eccentric butterfly valves typically have lower operating torques due to their eccentric design.
