Detail Description
1. ATECO U.K. Float Operated Cover Valve is designed to operate outside of the emergency drain nozzle connected to complete emergency drainage systems on the tank.
2. When the rain water rises up to the float, it opens the emergency roof drain float operated cover. So, it prevents vapour loss of the drain system and keeps product vapour loss in the floating tank.
