Dixon SBC500ALFL MannTek Safety Breakaway Coupling, 5-inch size with 150# flanged connections on both ends. Aluminum construction provides lightweight durability and corrosion resistance. Designed for emergency disconnect protection in bulk transfer hose lines, preventing spills and equipment damage during pull-away incidents.

Applications

• Coupling is designed to minimize spillage and damage associated with drive away and pull away incidents.
• Typical applications: loading rack

Available Options

• Also available in NPT Thread, BSP thread, DN Flange, 300# ASA Flange, Grooved Ends or any combination thereof. Consult Dixon for more information.
• Optional Non-closure Design available, consult Dixon for more information. The non-closure design is an economical alternative which allows the coupling to break away due to pull-away/drive-away incidents thus protecting piping systems and equipment. The design allows spillage of product in these instances due to the lack of valving in the coupling. Useful applications where non-hazardous product is being conveyed and where there are no environmental concerns.

Features

• Designed to be installed between a fixed point (pipe, pump, manifold) and a hose
• Coupling automatically senses an excessive load, closes the valves and disconnects
• High flow rate / low pressure drop

How It Works

• The safety breakaway valve consists of two halves, each with a valve that has an O-ring seal. When the safety break-away couplings separate, it allows the valves to close. The two valves close rapidly, minimizing exposure to personnel and the environment.
• Safety breakaway couplings have three external break bolts. In the case of axial tension all of the bolts take up the force corresponding to the break force on the hose with a safety margin. Non-axial forces concentrate the tension forces more strongly on one bolt, so that the safety breakaway coupling reacts in a natural way to the reduction of the hose break forces.
