Triple Offset Butterfly Valves

RAC triple offset design is ideally suited to metal seated butterfly valves providing a bi-directional zero leakage performance on high temperature, high pressure and firesafe applications.

This design eliminates friction completely between the seat and the disc seal ring  ensuring longer service life
