Abstract

A method for manufacturing a valve having a valve element with a passageway through it and a shank portion having an annular groove, the valve member being rotatably mounted within a plastic valve body having corridors of inlet and outlet, said method including the steps consisting of placing an annular closure substantially entirely inside said groove, placing the valve element inside the cavity of a mold having a configuration complementary to the external configuration of the valve body; introducing into the opposite ends of said mold cavity a pair of male elements having an external configuration complementary to the internal configuration of the valve body, each of said male elements having an inner end portion which is located inside the corridor of the valve member, and an annular flange disposed so as to engage the adjacent portion with said valve member surrounding the passage) to introduce plastic material under high pressure and a high velocity flow into said mold cavity to mold the body of the valve around the valve element and the male elements, and remove the male elements from the valve element passage and the molded body of the valve.
