Product description
Fluorine-lined flanged ball valve is a common valve on modern anti-corrosion industrial pipelines. The internal flow channel of the ball valve and all parts in contact with the medium are lined with high-tech fluorine, which has good corrosion resistance. When it works, the center of the sphere and the sealing surface rotate without clearance, and it has a good sealing performance. It is especially suitable for pipelines with concentrated acid, sulfuric acid, aqua regia and various corrosive liquids. As the connection of the pipeline and the adjustment of the medium.
Features
1. Its spherical center hole and flow channel are straight-through, so that the ball valve has a large flow capacity and can effectively reduce the retention of the medium.
2. The internal flow channel of the ball valve and all parts in contact with the medium are lined with high-tech fluorine, which can be applied to various corrosive media.
3. The configuration of the actuator can be selected according to different usage conditions, such as pneumatic, electric, on-off type, or intelligent adjustment type with positioner.
