Applications
Available Options
- Also available in 150# Flange, 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.
- O-ring Kit: O-ND4-01
- Breaking Bolt Kit: S-N4D-44
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 breakaway 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.
WARNING: This product contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.
