Non-Closure Breakaway Couplings

Non-Closure Breakaway Couplings

Technical Specification (Non-Closure)

non closure breakaway couplingAvailable in both Industrial and Marine versions, these KLAW Couplings can be installed between a flexible hose string or fixed to a rigid point. 







Non-Closure Couplings are specifically designed to incorporate an identifiable safe parting point within the transfer system.

KLAW recommends this type of coupling only where the medium (product) in non-hazardous and media spillage is acceptable.

Is the coupling hygienic?

As is standard for the industry, this coupling, although clean for service, are not specifically hygienic.

KLAW is able to offer hygienic polished couplings complete with no “Bug Traps” to ensure they comply with industry standards set down by the FDA.

These hygienic couplings have seen recent increase in demand within the agricultural market where the media is not hazardous but the equipment is a valuable asset to protect.

When will the coupling activate?

KLAW has both Industrial and Marine models to ensure a required activation can be achieved in accordance with the users desired operating conditions.

Activation with KLAW Industrial Non-Closure couplings is generated through the Axial force being applied, where as with the KLAW Marine Non-Closure couplings activation is generated through a linear pull.

Alternatively, activation will occur through a flow pressure surge beyond the predetermined breaking force.
