① The unique three-eccentric design of the sealing surface between the friction drive, extending the service life of the valve.
② torque generated by the elastic sealing.
③ ingenious wedge design makes the valve more closed more tightly with the automatic sealing function between the sealing surface with a compensatory, zero leakage.
④ small size, light weight, compact, easy to install.
⑤ can be configured according to user requirements pneumatic, electric equipment, to meet the needs of remote and programmed.
⑥ replacement parts material suitable for a variety of media, and can be anti-corrosion lining (lining F46, GXPP, PO, etc.).
⑦ continuous structural diversification: wafer, flanged, welded.
The structure of the wafer type butterfly valve length according to GB12221-1989 requirements, flange dimensions according JB/T79-1994 requirements.
