      发布日期:[2020-01-07] 点击率:

      The butterfly valve is designed and manufactured by using a new type of structure form of central line type disc plate and short structure steel plate welding. It is compact in structure, light in weight, easy to install, small in flow resistance and large in flow volume, avoiding the influence of high temperature expansion, and easy to operate. There is no connecting rod and bolt in the body, which is reliable and has long service life. It can be installed in multiple stations, not affected by the flow direction of media.

      Features of vacuum butterfly valve:

      The valve can bear positive pressure;

      The valve rod does not move up and down;

      The direction of the air circuit is changed by the electromagnetic reversing valve, and the butterfly valve driven by the actuating cylinder is controlled to open and close.

      It is used to connect or cut off the air flow in the vacuum pipeline.

      The applicable medium is pure air and non corrosive gas.

      Optional feedback signal device and electric valve positioner.

      purpose

      The butterfly valve is a kind of non airtight butterfly valve, which is widely used in the production process of building materials, metallurgy, mining, electric power, etc. the medium temperature is ≤ 300 ℃ and the nominal pressure is 0.1MPa. It is used to connect, open and close or adjust the medium quality.
