Function and Description
In-Tank Valves for Cryogenic Storage Tanks Meeting API 625 Requirements
PROTEGO® ITV-S in-tank valves are used in storage tanks for cryogenic liquids in order to

stroke. The seal between the valve seat and the valve disk is ensured by finely lapped surfaces and achieves maximum tightness. The actuating unit, installed on the tank roof, is specifically designed for the requirements of the application and connected to the valve unit installed in the tank via suitable cables.
Fail-Safe-Concept
During normal operation, the valves are kept in the open position. The bottom valve is only closed in an emergency. In the event of an energy drop, the valve piston, due to its own weight, falls onto the valve seat which closes the bottom valve (fail safe concept).
