Ductile Iron Materials Electric Power Pressure 1.6 Mpa Flanged Butterfly Valve

Usage

The valve is widely used in various pipelines of water supply and drainage, building fire protection and other systems, especially in fire protection pipelines. The valve can be used in pipelines or equipment with non corrosive media for intercepting, connecting and regulating flow.

Structure and action principle

The valve is connected by flange. The valve is composed of valve body, disc plate, valve shaft, worm gear head and other parts

Operate the worm gear device, rotate the valve shaft by 90 °, drive the butterfly plate to rotate by 90 °, and realize opening or closing. Due to the characteristics of worm gear device, the flow can be adjusted arbitrarily.

Valve features

1. The structural dimension complies with GB / t12221, with small volume, light weight and easy operation.

2. The structure adopts half shaft structure, which operates at 90 degrees and opens quickly; The disc plate has high strength, large overflow area, small flow resistance and energy saving.

3. The medium can flow in any direction from both sides of the flange butterfly valve, which can be connected or cut off.

4. Small operating torque, labor-saving and light.

5. The number of opening and closing tests is up to 10000, with long service life.

6. Achieve complete sealing, and the leakage of gas test is zero.
