Description

Applications

  • Coupling is designed to minimize spillage and damage associated with pull away incidents.
  • Typically used in ship-to-offshore platform and ship-to-ship product transfer operations

Features

  • Designed to be installed within a hose string where the coupling will have a length of hose attached to both sides
  • Coupling automatically senses an excessive load, closes the valves and disconnects
  • Release is executed when force causes bolts to break

Construction

  • 316 Stainless Steel body
  • FKM O-rings

How It Works

  • The safety break-away 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 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.
