Ace Roto-Mold Threaded Vented Lid & Ring

Den Hartog Threaded Vented Lid & Ring with Air Breather, is a special type of relief valve specifically designed for tank protection. The Breather Valve is a protection device mounted on a nozzle opening on the top of a fixed roof atmospheric storage tank. Its primary purpose is to protect the tank against rupturing or imploding. Without an opening or a controlled opening, a fixed roof atmospheric tank would rupture under increasing pressure caused by pumping liquid into the tank or as a result of vapor pressure changes caused by severe thermal changes.
