Safety breakaway couplings ABOV series

ABOV series breakaway couplings separate the line at a defined tensile load, but do not close the two line ends.  The tensile load should be selected with a sufficient safety margin below the load limit of the line, such as the maximum permissible tensile load of a hose line.
Unlike the ABV series breakaway couplings, the ABOV series breakaway couplings are not fitted with valves that can safely close both line ends to prevent product leakages in the event of a separation. For this reason, these breakaway couplings are particularly suitable for loading media that are non-critical to humans and the environment. As such, they represent a cost-effective alternative to automatically closing breakaway couplings. The breakaway coupling releases in the same way as the ABV series when three predetermined breaking points, or 
breaking pins, are broken. As with other RS breakaway couplings for industrial use, the design of the coupling does not impose any restriction of the load angle of the line ends. The ABOV will safely release at a traction angle of up to 90° from the line axis.
The nominal breakaway force is configured for a purely axial tensile force, which acts evenly on all three breaking pins. In this case, it is at its highest level.
In the case of lateral breakaway, the tensile force only acts on one or two breaking pins. In this situation, the breakaway force is correspondingly lower.
Even without the automatic shutter used on other breakaway couplings fitted with valves, the ABOV breakaway coupling can provide the hose line and plant components with effective protection against disproportionate tensile loads.
If the media being loaded do not pose a hazard to humans and environment and the loss of medium does not cause any significant economic loss, this represents a cost-effective protective device for the connected plant components.
