D673W Pneumatic butterfly valve

D673W Pneumatic butterfly valve

Overview

D673W Pneumatic butterfly valve adopts a precision J-shaped elastic sealing ring and a three-eccentric multi-level metal sealing structure. It is widely used in metallurgy, electric power, petrochemical, and industrial pipelines such as water supply and drainage and municipal construction. Adjust the flow rate and cut off fluid usage.The valve by three eccentric structure,and the butterfly-valve seat sealing surface are of different hardness and stainless steel production,which will have a good corrosion resistance,wearability,long life,with two-way valve sealing function.This kind of butterfly valve is suitable for food, pharmacy, petroleum chemical, power station, steel plant,

water treatment of industrial environmental protection and urban pipeline system as the best device for regulating and cutting off the liquid.

Features

D673W Pneumatic butterfly valve

1,Triple eccentric sealing structure, the valve seat and butterfly plate are almost wear-free, and have a tighter sealing function.

2,The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has good sealing performance at high temperature and low temperature, and has long corrosion resistance and long service life.

3,The valve body is resistant to corrosion, high temperature and abrasion, and has a long service life.

4,Large sized board is adopted truss structure which is high strength,bigger flow area and low flow resistance.

5,With two-way sealing function, the valve can be installed in any direction because you do not have to consider the medium flow direction and the space.

6,Driven device can be installed in multi-position(90℃ or 180℃ rotation),convenient to use.
