Check valve

摘要

A check valve is positioned in and between opposed tube ends and includes a valve body having a valve seat engageable by a valve element having a stem extending centrally of peripherally spaced apart elements interconnected by an annular end shoulder engaged by a keeper which receives the outer end of the valve stem and holds a coil spring against the valve element. The valve assembly is disassembled by manipulating the keeper against the spring out of engagement with the annular end shoulder.
