Safety Breakaway Couplings
Safety Breakaway Couplings (SBC) are used to prevent spillage and damage associated with drive-away or pull-away incidents at terminals and loading or unloading points.
The Safety Breakaway Couplings are designed to act as the weakest link in the hose line or loading arm, ensuring efficient operations and minimal downtime.
| Size from: | 1”-12” (cable release type 1”-8”). |
| Material: | Aluminium, Stainless Steel, Brass. |
| Seals: | FKM seals. |
| Working pressure | 25 bar (varies depending on material). |
Poppet design – avoid damaged valves seat or over rotating flip.
Marine type
Marine Breakaway will not release in any angular pull, only at straight pull.
Marine Breakaways should always be installed between two strings of hose.
Industrial type
Industrial Breakaway will release in any angle from 0-90 degrees.
Industrial Breakaways should always be installed to minimum one fixed point.
Cable release type
In service
The coupling consists of two halves, each with a valve.
Released
After an emergency disconnection the coupling separates and both valves close immediately.
Connections
SBC – Breaking pin
Safety Breakaway Couplings
Benefits
Low breaking force
Low breaking force.
Sideload
Withstands extreme sideload.
Connections
Choose inlet and outlet connections individually - any combination of connection available. After activation, the unit can be reset in minutes without special tools. Reliable poppet valve design. No nipples or reducers necessary - produced with a wide range of flanges and threads. Available with integrated hose shank.
Sealing
Unique low temp FKM sealing technology for all qualities of LPG and temperatures operational.
