How it works

Turning the hose unit 15° clockwise locks the units together. The valves are still closed and are not opened until a further rotation of 90° has been performed and then the product flow is guaranteed. To close the valve and to unlock the units, reverse the procedure.

  • Valves open and close automatically on connection and disconnection.
  • Simple single action operation, no levers or switches to operate.
  • Valves are guaranteed closed prior to disconnection.
  • Minimal residual loss on disconnection (e.g. maximum 0.35cc for 2" DN50).
  • Will connect and disconnect under pressure and flow where necessary.
  • Extremely reliable, very few moving parts.
  • Robust construction, no external operational components.
  • Available with selectivity system to prevent cross contamination.
  • Reduces spillages to virtually zero.
  • Dramatically improves both operational and fugitive emission performance.
  • Reduces the possibility of human error in transfer operations.
  • Improves efficiency.

Virtually zero spillage
