Stainless steel butterfly valve (also known as stainless steel flap valve) with three eccentric multi-layer metal hard seal structure, is widely used in the medium temperature ≤425℃ gold, electric power, petrochemical, as well as water supply and drainage and municipal construction and other industrial pipelines, for regulating flow and load cut-off body use. The valve adopts three eccentric structure, the valve seat and plate sealing surface are made of different hardness and stainless steel, with good corrosion resistance and long service life. Butterfly valve opening and closing part is a disc-shaped butterfly plate, rotating around its own axis in the valve body, so as to achieve the opening and closing or adjusting valve called butterfly valve. Butterfly valve fully open to fully closed is usually less than 900, the butterfly valve and the butterfly rod itself does not have a self-locking force, in order to the positioning of the butterfly plate, to install a worm gear reducer on the valve stem. The use of worm gear reducer can not only make the butterfly plate self-locking ability, so that the butterfly plate stops in any position, but also improve the operating performance of the valve. The characteristics of industrial special butterfly valve can withstand high temperature, the applicable pressure range is also high, the nominal diameter of the valve is large, the valve body is made of carbon steel, and the sealing ring of the valve plate is made of metal ring instead of rubber ring. Large high temperature butterfly valve is made of steel plate welding, mainly used in high temperature medium smoke duct and gas pipeline.

Advantages:

1. Easy to open and close, labor-saving, small fluid resistance, can be often operated.

2. Simple structure, small size, light weight.

3. It can transport mud and accumulate less liquid at the pipe mouth.

4. Under low pressure, good sealing can be achieved.

5. Good adjustment performance.

Features:

Butterfly valve has the characteristics of simple structure, small size, light weight, material consumption, small installation size, quick switching, 90 degrees reciprocating rotation, small driving torque, etc., for cutting, connecting, adjusting the medium in the pipeline, with good fluid control characteristics and closing sealing performance.

How:

Connection: flange, wire or welding.

Driving mode: manual, electric, pneumatic, bevel gear, spur gear rotation.

Applicable media: water, oil, gas, steam, etc.
