The patent number for the fluorine-lined bellows single-seat control valve is ZL200920188414.6. ▪ The fluorine-lined bellows single-seat control valve is an invention patented by the company; it consists of an actuator and a straight-through fluorine-lined bellows control valve assembly. The valve body assembly can be combined with pneumatic or electric actuators to create various types and specifications of control valves. ▪In a fluorinated bellows control valve, a bellows assembly is installed inside the upper valve cover. The top end of the valve core is sealed to the lower end of the polytetrafluoroethylene bellows, while the upper end of the bellows is sealed to the upper valve cover and the piping using bolts and nuts. In this way, the bellows isolates the medium from the outside environment, ensuring a good seal, and allows the valve core to move freely up and down, which demonstrates the advantages of bellows sealing. ▪Since the inner cavities of the valve bodies are lined with corrosion-resistant fluoroplastics (PTFE, FEP, PFA), they are widely used in any corrosive medium except \"molten alkalis and elemental fluorine\". ▪Drive type: electric, pneumatic, electro-hydraulic. ▪Lining materials: PTFE, FEP, PFA, GXPO, etc. Haichuan Pump and Valve Group
