rubber lined diaphragm valve

FREE-VALVE Normally Closed Pneumatic Operated Fluorine Lined Diaphragm Valve is composed of single-acting pneumatic actuator and diaphragm valve, which uses pneumatic actuator to drive the opening and closing of the diaphragm valve, and the valve is kept in normally close state in the case of no air source or no signal, and the valve is in a opened state after the cylinder is ventilated, so as to act as an opening and closing mechanism to control the flow of medium.

FREE-VALVE’s manual fluorine lined diaphragm valve is a special form of on-off valve, disc is a diaphragm made of corrosion-resistant soft material,the diaphragm separates the bottom body cavity from the top bonnet cavity

FREE-VALVE’s manual Fluorine-Lined Corrosion Resistant Diaphragm Valve is a special form of on-off valve, disc is a diaphragm made of corrosion-resistant soft material,the diaphragm separates the bottom body cavity from the top bonnet cavity, so that the stem, metal disc and other parts above the diaphragm are not subject to media corrosion,so fluorine lined diaphragm valve eliminate the packing seal structure, and will not produce media leakage.
