The characteristic of UPVC or connected diaphragm valve is that the diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, valve clack and other parts located above the diaphragm are not corroded by the medium, and the packing seal structure is omitted. Will produce medium leakage. The inner cavity partition is a diaphragm made of rubber or plastic with a soft seal, which has good sealing performance.
