Dixon Safety Break-away Couplings - Breaking Bolt Series

Description:

Industrial and Marine Versions

Coupling Category

Dry Disconnect Fittings

Manufacturer

Dixon Dry Disconnects Fittings

Industrial Version

The breaking bolt industrial breakaway coupling is designed to minimize spillage and damage associated with drive away and pull away incidents

  • 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
  • female NPT is standard, optional ANSI / DIN flanges or male NPT are available
  • stainless steel or aluminum
  • working pressure: stainless steel 360 PSI and aluminum 230 PSI at ambient temperature (70°F)
  • Viton® is standard seal

Marine Version

The breaking bolt marine version break-away coupling is designed to minimize spillage and damage associated with pull-away incidents.

  • designed to be installed within a hose string where the coupling will have a length of hose attached to both sides
  • typical applications include: ship-to-offshore platform and ship-to-ship product transfer operations
  • coupling automatically senses an excessive load, closes the valves and disconnects
  • release is executed when force causes bolts to break
  • female NPT is standard, optional ANSI / DIN flanges or male NPT are available
  • working pressure: 360 PSI at ambient temperature (70°F)
  • 316T1 stainless steel body with VitonĀ® O-rings

How it Works


Safety break-away 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 break-away coupling reacts in a natural way to the reduction of the hose break forces.

The safety break-away valve consists of two halves, each with a valve that has an O-ring seal.
AFTER emergency disconnect AFTER

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.





Optional Non-Closure Design

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. This design allows spillage of product in these instances due to the lack of valving in the coupling.
Useful in applications where non-hazardous product is being conveyed and where there are no environmental concerns. Available in both Industrial and Marine versions. Consult JGB for more information.
