Vent-check Valve

A dual purpose marine valve used primarily with shipboard cargo tanks and bulkheads. It acts both as a vent valve, to relieve vacuum and pressure, and a check valve, to prevent cargo contamination. It is equipped with an internal flame screen and/or a protective mesh and may include a hinged cover.
