PFA butterfly valve adopts upper and lower four O-rings, the center of the sandwich Viton, and combined with the pressure of the butterfly spring, Viton expands and enhances the sealing performance, solving the problem of media leakage. The butterfly plate and valve stem adopt one-piece design to prevent the valve stem from flying out and reduce the installation gap. The upper body and lower body adopt split structure and hexagonal screw connection. When the valve is used for a long time, fluorine plastic wear or shrinkage can be adjusted on the valve body hexagonal screws (small diameter valves to leave 1-3mm space to adjust the use). Each adjustment will be able to achieve the effect of extending the service life.
