D363H welding hard seal butterfly valve is suitable for heating pipeline, oil, gas pipeline and other major industrial pipeline valves, this design makes the valve for high temperature, fire ideal hard seal butterfly valve

Use for

D363H welding hard seal butterfly valve is suitable for food. Pharmaceutical, petrochemical, power plants, steel mills, industrial environmental protection water treatment and high-rise buildings. A good device for regulating flow and cutting off fluid on the supply and drainage pipeline. Butterfly valve is suitable for high temperature, high pressure, fire protection, heat preservation and other pipelines as opening and closing or adjusting medium.

Specialty

1.compact structure, small volume, light weight, flexible operation, easy to use

2.Using three – dimensional eccentric elastic or multi – layer hard seal structure, the sealing performance is reliable to zero leakage

3.This valve has no flange, which brings great convenience and beauty

with pipe and bull-guarding bandaged

4.With high temperature, high pressure corrosion resistance, wear resistance

Worm drive, pneumatic drive, electric drive
