Lined valve

Steel lined PTFE discharge variable diameter ball valve is an industrial valve, particularly suitable for the treatment of corrosive media. The cast steel valve body is usually lined with PTFE such as PFA, FEP, PTFE, etc., because the material has excellent anti-corrosion performance, it can ensure that the valve body is not corroded by the medium. When the product needs to be discharged, the variable diameter port of the ball valve is determined by the material. The small-sized end is connected to the discharge tank, and the large-sized end is directly discharged. Therefore, the combination of one large and one small size can better discharge the material without blockage. The working principle of the fluorine lined ball type discharge valve is to rotate the ball to make the valve smooth or closed. The valve disc and the inner side of the valve body are all made of fluorine plastic lining technology. It has the advantages of lightweight switch, small volume, reliable sealing, simple structure, easy maintenance, and wide range of use.
