The invention relates to the technical field of valve control meter shell manufacturing, in particular to a stainless steel valve control meter shell and a manufacturing method thereof, and the method comprises the steps of manufacturing a metering cavity pipe section, a ball valve cavity pipe section, a water inlet pipe, a connecting pipe and a water outlet pipe and welding to obtain the stainless steel valve control meter shell. Compared with a valve control meter shell manufactured by using an integral casting process in the prior art, a forming mold is not used, the problems of high cost and short service life caused by the forming mold are solved, the problems of long production period and long machining time are also solved, the cost is reduced, and the finally formed valve control meter shell is small in mass and does not have the defects of sand holes, air holes and the like. Compared with a valve control meter shell manufactured by using an integral welding process in the prior art, the valve control meter shell has the advantages that the machining procedures of blanking, deep drawing, chambering, rotary cutting and the like are not needed, and the selected existing pipe fitting is hollow, so that parts such as a valve rod matching middle hole, a valve mounting hole and the like do not need to be machined, and the problems of complex process and more cutting wastes caused by a machining process are solved.
