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 seal off discharge lines in the event of an accident or emergency. These devices meet the Requirements of API 625.
The PROTEGO® ITV-S consists of a valve guide unit with elbow and valve seat which is mounted on the inside of the tank wall. This unit accommodates the valve piston and guides it over the entire lift 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).
