Breakaway couplings (safety breaks)
- Protection of human health and the environment from hazardous substances
- Suitable coupling technologies for different demands
- Avoidance of losses of media
- Protection of load lines
- Customised special designs from DN 25 to DN 300
Breakaway couplings (also called safety breaks) are safety components. They are used during the loading processes to prevent the most serious safety hazards: The unwanted and disproportionate tensile load on the load line, caused, for example, when tankers and trains drive off too soon or by ships drifting.
Such tensile loads can mechanically damage or even destroy both the connection points and the load line itself, which could even lead to uncontrolled leaks of the fluid to be loaded, resulting in the corresponding risks to people and the environment. That is why breakaway couplings are finding increasing use as the standard when loading hazardous media (caustic, toxic, explosive, etc.) in order to prevent industrial accidents.
Depending on the application, widely differing technical designs are needed to reliably implement both functions. So only a specialist is able to competently select and design the suitable type, which means individual requests and advice are always necessary. That is why on these pages we are limiting ourselves to the basic disc valve technologies typically used in a wide market.
For special and niche applications, we have a whole range of special technologies on hand for you and would also be happy to adapt them to your individual application. Get in touch with us!
More information
Breakaway couplings are typically equipped with two functions to accomplish that:
- Function 1) A defined separating mechanism that triggers sufficiently earlier than the load limit and separates the line between the mobile unit and the loading system.
- Function 2) A spontaneous automatic shutter for both sectioning points to prevent the fluid from leaking.
ABV breakaway couplings prevent accidents by protecting hoses or pipework from excessive load, including non-axial forces which can reduce the breaking strain of a hose. When ...
ABV-S breakaway couplings ensure safe loading and unloading when fluids are being transferred to or from road, rail or ship tankers. The mechanically activated ...
