Double Offset Butterfly Valve - Cast Iron, Dn800, Manual Operation | Bi-directional Zero Leakage, Integrated Stainless Steel Ring, Double Eccentric Design

We are a reputed name in this industry as a Manufacturer & Exporter of Double Offset Butterfly Valve in Wenzhou, Zhejiang, China. Double offset butterfly valve is mainly used for power generation, petrochemical processing and other applications involving water or air as a medium.

Features:-
1.Design standard acc. to AP609, ASME B16.34, EN593 and AWWA C504
2.Double eccentric structure to allow easy opening minimized friction.
3.The soft rubber seal is attached with a stainless steel seat structure ,providing dual seal and bi-directional zero leakage.
4.The valve seat with integrated stainless steel ring has a mirror finish surface, reducing friction and prolonging service life. The disc seal comes with a "T-shapeda cross section seal structure. This not only prevents blowouts under a vacuum environment, but also offers optimum seal with the adjustable compression level.
5.The stem axial seal stuffing box has a double V-packing structure. This structure can effectively shut off the contact between atmosphere and the medium within the pipe when pressure fluctuates.
