Butterfly valves with single or double offset construction do not perform to the expectations when used for harsh & severe process applications, such as extreme temperature conditions, steam isolation, high operational frequency, abrasion services etc. Triple offset butterfly valves provide reliable & efficient performance under these harsh applications.
Series 7600 Triple offset metal seated Butterfly valves with unique seating geometry & design disc-shaft engagement provide high cycle life under extreme temperature conditions. With metal to metal tight shut-off characteristics eliminates.
