TRIPPLE OFFSET BUTTERFLY VALVES

Series 7600 Triple Offset Metal Seated Butterfly Valves With Unique Seat Geometry Disc-Shaft Engagement Provide High Cycle Life Under Extreme Temperature Conditions With Metal To Metal Tight Shut-Off Characteristics. Eliminates All Those Problem Like Wear, Seat Deformation, Abrasion, Cold Flow & Seat Leakage.

Butterfly valves with single or double offset construction do not perform to the expectations whenused for harsh & severe process applications, such as extreme temperature conditions, steam isolation, high operational frequency, abrasion services etc. Triple offset butterfly valves providereliable & 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 metalto metal tight shut-off characteristics eliminates. all those problem like wear, seat deformation, abrasion, cold flow, crutches & leakage which aregenerally associated with soft seated butterfly valves. With extended performance features series7600 Butterfly Valve are suitable for following application.

The Laminated Seal 

The torque transmitted by the shaft to the disc generates uniform seating forces on the entire circumference of disc seal. The laminated seal flexes & gets energized in the direction of seal all over its entire circumference The
resiliency of the disc seal allows valve body and disc to expand or contract without producing any jamming effect under the fluctuating temperature range. The torque generated radial compressive force, equally distributed around the circumference, provides bidirectional tight shutoff .
