Dry Cryogenic Couplings

The Dry Cryogenic Coupling consist of a “tank” unit wich is a type of a non-return valve and a “hose” unit with a valve driven by an internal cam curve to open both valves at the same time. Operation is a single action using a straight forward turning motion to connect the couplings and open flow path. An initial push and turn action on the hose unit provides engagement with the tank unit, thus locking and sealing the two units together. Further rotation opening the internal valves, thereby allowing full flow with a minimum of pressure drop.

A selectivity (code) system allows the system to be used to a wide range of cryogenic liquefiedgases without any risk of failure owing to “human error”.

Applications

Container discharge

Fuel bunkering

Loading/unloading of tank trucks, rail tankers, bunkering and tank vessels

Vapor recovery lines

Easy to handle

Push and turn - free flow.

Turn and pull - closed.

Safe

The valve cannot be opened until the unit is coupled and closes automatically when disconnecting.

Environmentally friendly

Accidental spillage eliminated.

Reliability

No loss or spillage of liquids at connection or disconnection.
