Internal valves for added cryogenic tank spillage protection

Internal valves are primarily designed for loading and unloading of CO2 and are found in delivery trucks and stationary storage tanks with flanged connections where they reduce the risk of spillage in case of broken pipe connections or truck accidents. They are frequently installed in conjunction with compressors and/or pumps and enhance the tanks safety.

Product description

The combined inner functionality of an excess flow valve and a ball valve provides a dual security for shutting off the flow in case of emergency – either manually by use of the lever or automatically if pressure changes dramatically.
