Worm gear PTFE butterfly valve

Short Description:

1. The butterfly plate of fluorine lined butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0 ° and 90 ° and when the rotation reaches 90 ° the valve plate is fully open.
2. Due to the limitation of structure characteristics, fluorine lined butterfly valve is not suitable for high temperature, high pressure, corrosion resistance, wear resistance and other industries.
3. Fluorine lined butterfly valve, as a component used to realize the on-off and flow control of pipeline system, has been used in petroleum, chemical, metallurgy, hydropower, etc

    Product profile

    The pneumatic butterfly valve is widely used in metallurgy, electric power, petrochemical, municipal construction of water supply and drainage and other industrial pipelines with medium temperature ≤ 250 ℃ to regulate flow and cut off fluid. The butterfly valve adopts spherical seal, floating seal structure and eccentric structure, with long service life. The valve has two-way sealing function, and the product meets the GB / t13927-2008 valve pressure test standard and other standard.

    Product features

    1. The valve adopts eccentric structure, and the valve seat and valve plate are almost free of wear. It has the sealing function that the closer it is closed, the tighter it is.

    2. No matter in the case of low pressure or high temperature, it has excellent sealing performance, corrosion resistance and long service life.

    3. The sealing surface of butterfly valve is overlaid with cobalt based hard alloy, which is wear-resistant and has long service life.

    4. The valve has a two-way sealing function, and can be installed in any direction without the restriction of medium flow direction and the influence of space position. The driving device can be installed in multiple positions (rotated 90 ° or 180 °), which is convenient for users.
