Purpose and characteristics 

The ZS4-L15E MDCV is an improved design based on ZS series. Brand new streamline design is adopted for valve outline to obtain beautiful appearance; overflow valve is changed into a dynamic damping structure to enhance pollution resistance; and cast iron pressure regulating part is changed into all-steel threaded plug-in type to eliminate a phenomenon of easy damage of pressure regulating cover. The ZS4-L15 MDCV is completely the same as the ZS-series MDCV in installation and connection dimensions, oil line type, slide function and return mode.
