Cast steel WCB lined PTFE plastic butterfly valve, usually made of PFA, PTFE, FEP, PO and other materials as the lining material for the valve passage. The butterfly valve is a valve body cast from carbon steel WCB material, and the butterfly valve is fixed and clamped on both sides of the pipeline with flange plates. The worm gear actuator can make the valve opening and closing more convenient, fast and labor-saving. The installation of the clamp on the pipeline can effectively save pipeline space, reduce costs, and prevent corrosion from corrosive media. It is a type of corrosion-resistant and acid alkali resistant valve.
