The main advantage of the Triple Offset Butterfly Valve is that the disc and seat close without rubbing. They only come into contact at the fully closed position, which eliminates a major source of wear. The end result for high precision brands is bubble tight, zero leakage shutoff.
This allows us to continuously meet critical requirements with reliable performance in applications as diverse as high temperature, cryogenics, water transmission, hydro-power, hazardous gases, emergency shut-down and nuclear plant safety systems.
