How it works
The Dry Aviation Couplings include a bayonet-type connector and are flanged or threaded to suit installation requirements. Each tank unit contains a “fail safe” springloaded valve seating on a tapered seat. The valve is controlled by the action of coupling and uncoupling the hose unit. |
 To Connect
Push and turn
-It´s coupled
-full flow |
 To disconnect
Turn and pull
-It´s realised
-no spillage |
| When connecting the DDCoupling
the hose unit will
slide easily over the tank unit.
The three rollers engage in the
three slots.
To allow the hose unit to lock,
rotate the hose unit clockwise
approximately 100° whilst
gently pushing towards the
tank unit.
To stop the flow and unlock
the units, reverse the procedure. |
