PN1.6 MPA Carbon Steel Body And Disc, Flanged Butterfly Valve

Usage:

The valve can be used in the pipeline or equipment for the closure, connection and regulation of flow

Connection size:

Main part material

The valve features:

The valve is worm drive, flange connection, JB/T 8527 design standard, three eccentricity

Butterfly valve that the butterfly plate rotation axis (stem axis) and the butterfly plate sealing surface of a deviation, the seat rotation

The axis and the valve body flow channel axis form an Angle. The valve consists of a valve body, a butterfly plate, a valve stem and a butterfly plate

Sealing ring, butterfly plate pressure ring, bracket, end cover, and other parts.

2. Through the cochlear operation, the valve stem rotates 90° and the butterfly plate rotates 90°, so as to realize the opening

On or off. Because the product is three eccentric structure, it can produce a CAM effect in the process of opening and closing

Should, reduce the valve switching torque, reduce the wear between the seat and the butterfly plate, prolong the valve

The service life of.
