Cryogenic Breakaway Coupling
The KLAW Cryobreak Breakaway Coupling minimises the risk of cryogenic media spills; this reduces the risk of both damage to assets and injury to personnel in the event of a drive-off or extreme pressure flow.
- Minimum headloss – reduces impact on your general operation.
- Compact and lightweight – enables easy handling and moving of the coupling.
- Simple to operate and maintain – each unit is supplied with a detailed Installation and Maintenance Manual.
- The KLAW Cryobreak takes advantage of KLAW Flip-Flap Valve and Breakstud technology.
- KLAW Flip-Flap Valve technology eliminates the risk of Partial Break – activation and therefore flow closure can be instigated with a single Breakstud release.

Shown Flip-Flap Valves within the two separated halves in the activated and closed position.
Operating temperatures to -196°C (-320°F)
Designed and manufactured for the safe transfer of media at cryogenic temperatures.
Operational advantages
- Light and compact
- More simple to maintain: Reset plugs with easy to reset procedure after maintenance or activation.
- ATEX cable is fitted as standard.
- No need for separate end connectors; but maintains the flexibility of multiple End Connections.
- Wrench spanner Flats included in the design for easy threaded end attachment.
- Option to include proximity switch to monitor transfer operations.
Typical applications
Large scale and small scale Ship Bunkering, Ship-to-Shore operations, Road Tanker refuelling and Bulk Storage, Fixed Bulk Storage operations, Rail Car Tender Cars, Loading Arm installations and retail dispense equipment for cryogenic service.
Typical media
- LNG
- Liquid Nitrogen
- Liquid Oxygen
- Ethylene
- Ethane
- Argon
- CO2
Delivers protection from:
- Road Tanker drive-off prior to disconnection.
- Shift or shunt of Rail Cars during loading or unloading operations.
- Over pressurisation of the transfer system beyond the engineered tolerance of the Breakstuds.
Breaking loads
Coupling break-loads can be varied to suit any particular application.
This Cryogenic Breakaway Coupling is designed to activate under a bending moment. The applied force being an angle of up to 90 degrees to the plane of the coupling.
