Soft Seal Bi-direction Butterfly Valve

1.Has isobaric bi-directional sealing performance, reliable sealing performance;

2.Small face-to-face dimension Among all kinds of valves, butterfly valve has the smallest Face-to-Face dimension, especially the wafer type butterfly valve’s face-to-face dimension is far smaller than nominal dimensions

3.Use semi-axial structure with large cross flow area and small flow resistance;

4.Use double eccentric structure, the valve body sealing surface is completely detached from the valve plate sealing surface after opening, no friction, long life cycle;

5.According to the requirement of the client, seating rubber seals may be optionally mounted on body or disc;

6.Open and close is quick and convenient with smaller force

The disc rotates 90 o that can open and close the valve because the medium force against each side of disc is almost equal and the resulted direction of torque is reverse, so the on-off torque is mainly decided by the abrasion torque of sealing surface.

7.Good regulating performance

By changing the rotation angel of the disc, the valve can classify regulating the flow of medium in the pipeline, opening indicator and limiting device are located on top of the butterfly valve.

8.Simple structure, small size, light weight, suitable for big size valve.

9.Horizontal mounting manual valve has bi-directional display function, the opening state of the valve can be observed synchronously from the operating surface and side.
