As opposed to standard breakaway couplings, the triggering force of the new ABVN Series coupling made by Roman Seliger is not dependent on the pressure within the line transporting the medium.
Based on practice, it is known that with flange connections the dimensioning of the screws is dependent on the internal
pressure of the connected lines, since the internal pressure attempts to press both flanges apart. This must also be considered in the dimensioning of breaking pins for current breakaway couplings. This effect is eliminated through a patent-protected measure applied to the ABVN series breakaway coupling. For the operator this means that the release force can be individually calibrated to the existing application. As a result, even hoses of low tensile strength (e.g. film wrap hose) or lines and equipment components under enormous pressure can be optimally protected from damage due to excessive external tensile loads. The breakaway coupling is suitable for use wherever pipe lines and hoses have to be protected from excessive loads. As opposed to the breakaway couplings in regards to the latest technology, the triggering force of the innovations presented here can then be individually selected, regardless of the line pressure.
