Sanitary grade manual butterfly valve multi position handle for regulating flow

Sanitary grade manual butterfly valve multi-position handle for regulating flow

Specifications

Description
The butterfly valve is designed and applied in the valves of separate delivery with the function of opening and closing.It realizes sealing by using the theory of compressed air.This kind of butterfly valve is equipped with ultra-small torque which standard butterfly valve is not.
Specification: DN100 - DN300, 4" - 12"
Operation mode: manual and pneumatic

Working principle:
To open valve, the seal will lose efficacy. But there will be no leaking.The gas in the valve will be sealed once valve is closed, remaining no friction in sealing parts.
Technical advantages:
To open and close valve, there won't be friction occurred in sealing part. Thus, there's no fear of contamination generated by the friction of sealing part.
