Carbon Steel Lug Type Eccentric Butterfly Valve Manual ANSI 300LB PN40
1. Elastic property of composite metal sealing ring to perform zero leakage.
2. Torque seal to ensure persistent bidirectional tightness with zero leakage.
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 degree rotation.
4. STL one-pice hard surface seat may adapt to working conditions,which is featured by long service life and easy maintenance.
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 flexible installation.
6. All metal structure and leak-tight performance meet with friesafety.
7. Anti-blowout stem for high depenedability, completely conforming to API609
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: Manual and Gear Box
