1750 Inverted Vent Check Valve
ABS Approved
For sizes larger then 4", please see our 1750 SEMICIRCULAR INVERTED VENT CHECK VALVES.
Our 1750 Inverted Vent Check Valve has a heavy duty hinge cover assembly prevents sea water from entering tanks in rough seas. The hinged cover can be visually seen from the bridge while in the open or closed position. The advantage to our design is the ability to visually inspect tank vents before any pumping sequences are performed. A stainless steel toggle bolt eliminates the need for any additional tools to open or close the cover.

The Inverted Vent Check Valve protects tanks and bulkheads from pressure build-up during loading and unloading of liquid or dry cargo and assure maximum efficiency during operations. The ball float prevents contamination of the tank cargo from sea water during heavy seas.
