Product Description

 

High Pressure, High Temperature, bi-directional, Zero Leakage Double offset Butterfly Valves.

The fire safe seated high performance butterfly valve incorporates two seats which function together to seal off pipeline flow. In normal operation, the soft seat provides a bi-directional "bubble tight" shutoff (zero leakage); the metal seat provides bi-directional shutoff in the event of a fire, in conformance to industry fire-safe requirements. Rigorously 100% internal tests prove bi-directional zero leakage seal.
