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.

100% instantaneous closure of both upstream and downstream flow – minimizes the risk of spills and clean-up costs.

Designed and manufactured for the safe transfer of media at cryogenic temperatures.

Operational advantages

[Back to top]
  • 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

[Back to top]

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

[Back to top]
  • 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

[Back to top]

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.
