Key features

The center line butterfly valve is concentric with the entrie butterfly plate and seat within a 360 circumference(center line).With two-way sealing function,pressure and flow can be freely adjusted.

Four level loading elastic seal absolutely ensures zero leakage inside and outside the valve.

A.Reasonable interference between the special transition curve at the circumferential connection of the shaft head and butterfly plate and the seat.

B.The end face of the shaft head is composed of elastic O-ring,a rigid gasket at the shaft shoulder,and elastic rubber gasket.

C.The radial direction of the shaft adopts the combination of O-ring and metal gasket.

D.The seat is embedded in an elastic body groove.

Adjustable elastic marble positioning is adopted,with accurate positioning and simple structure.

Design standards : Comply with HG/T 3704. GB/T 12224. ASME B16.34.

Driving mode:Manual,worm gear transmission,Pneumatic,Electric

Butterfly valve is with the stem rotation of the butterfly plate for opening and closing parts,to achieve the opening,closing and adjustment of the valve.
