Abstract

It is produced by placing the valve body in a mould, then inserting a pair of cores, which have internal end sections inserted into the valve body. Ring-shaped flanges are in contact with adjacent parts of the valve body. Plastic is introduced into the mould to form the valve housing around the valve body and cores, after which the cores are removed from their housing.
