Tank Air Escape Valves allow free passage of air into tanks, dry cargo holds, or storage space. They protect tanks and bulkheads from pressure build-up during loading and unloading of liquid or dry cargo and assure maximum efficiency during operations.
Since tank air escape valves to not have a float or automatic closing, they are used in locations not accessible to sea water.
All steel castings are hot dipped galvanized. All aluminum castings are anodized.
