Difference The difference between hard and soft seals Hard seal butterfly valve: the sealing pair is called "hard seal" on both sides of the seal. The seal has poor sealing performance, but it is resistant to high temperature, abrasion and mechanical properties. Such as steel + steel, steel + copper; steel + graphite; steel + alloy steel; (the steel here may also be cast iron, cast steel, alloy steel may also be surfacing, spraying alloy steel. Gold).
Soft Sealed Butterfly Valve: metal material on both sides of the seal, and flexible nonmetallic material on the other side is called "soft seal". This seal has good sealing performance, but it is not resistant to high temperature, easily worn and mechanically poor. Such as steel + rubber, steel + tetrafluoro [wiki] polyethylene [/ wiki]; and other rotor pumps.
The advantages of the soft sealing butterfly valve are good sealing performance. The disadvantage is that it is easy to wear out and wear, and the service life is short. The hard seal butterfly valve has a long service life, but the sealing property is worse than that of the soft seal.
