CHECK VALVE MODULE

摘要

A check valve module includes a body having a first fluid communicating surface and a second fluid communicating surface, and two one-way check valves in the body controlling flow between the first and second surfaces. One of the valves permits flow from the first surface to the second surface, and the other valve permits flow from the second surface to the first surface. The body also has an outer sealing surface between the first and second fluid communicating surfaces.
