Class 150 Stainless Steel Eccentric Butterfly Valve , Flanged
Triple Offset Butterfly Valve
1. Elastic property of composite metal sealing ring to perform zero
2. Torque seal to ensure persistent bidirectional tightness with
3. The design of right-angled rotacting with zero friction is
implemented by the distinctive triple eccentric principle, it
eliminates the frictionbet-ween the seat and sealing ring in 90
4. STL one-pice hard surface seat may adapt to working
conditions,which is featured by long service life and easy
5. One piece cast (Sheet welded) body, face to face dimnesion
confirming to ISO5752, ASME B16.10 and API609, replacement to high
performance butterfly valves and other types of valves,easy and
6. All metal structure and leak-tight performance meet with
7. Anti-blowout stem for high depenedability, completely conforming
8. The valve position indicator on the stem and the flange mounted
at the top are in favor of the indication of disc position.
9. The stem of triple eccentric butterfly valve is a shaft, stem
and disc are connected by key or pin-key combination.
10. Operation: Lever, Gear box, Pneumatice, Motor.
