Size shown 1” DN25	Size shown 2” DN50

Available in sizes:

¹⁄₂” DN13 –  1” DN25 –  1¹⁄₄” DN32 – 1¹⁄₂” DN40 – 2” DN50 – 2¹⁄₂” DN65 – 3” DN80 – 4” DN100

The latest in Cryogenic Breakaway Coupling technology

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.

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.
