ABSTRACT:
A solenoid operated valve assembly formed of a ferromagnetic end stop section and body section, an orifice section and a sleeve section of low magnetically permeable material. The sleeve section has an inner chamber with a centrally disposed portion of reduced diameter. Each of the sections is completely finished before assembly so that no further finishing operations are required. Predetermined sections are selected and a valve assembly is assembled by threading one end of the sleeve section to the end stop section and the other end to the body section. The orifice section is threaded to the body section to form a completed valve assembly.
