Multiple connection options: wafer type, lug type and flange type, which are used for water, cooling water, gas and powder. It can be used to regulate and cut off the flow of fluid.
The flow channel of center line-type butterfly valve is lined with rubber, with special design and compact structure. Butterfly valve use frame structure, with 2-way sealing function and not limited by the medium flow direction.
The surface of valve is coated by Epoxy resin grease, which is preventing corrosion.Different kinds of sealing materials can be used in different conditions.
The butterfly plate of fluorine lined butterfly valve is installed in the diameter direction of 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 the valve is fully open when it is rotated to 90 °
Fluorine lined butterfly valve and rubber lined butterfly valve are widely used in many fields, such as petroleum, chemical industry, metallurgy, hydropower and so on. In the well-known butterfly valve technology, its sealing form mostly adopts the sealing structure, and the sealing materials are rubber, polytetrafluoroethylene, etc
