MODULAR TWO WAY CHECK VALVE CONSTRUCTION

摘要

A check valve construction is provided which includes a housing having a first flow path and a second flow path. Liquid flow is controlled within the first and second flow path by movable plungers having a sealing surface and a plurality of prongs that control the length of movement of the plunger within the housing. One of the plungers permits liquid flow while the other of the plungers prevents liquid flow in response to pressure change within the flow paths.
