Ball Valve Spanners

If the valve is to be assembled to a skin fitting, ensure that the position of the skin fitting is such that it will be in a protected area, but readily accessible.
Ensure threads of mating fittings have a parallel thread and it is clean and undamaged.
Apply sealing tape or other suitable thread sealant to the thread of the Skin Fitting or Tail.
Screw ball valve onto the mating fitting using the correct Ball Valve Spanner (see sizes below).
Tighten any attached fittings to a maximum of 16Nm (12ft/lbs).
Check that the final position of the Ball Valve is such that it allows full movement of the handle from the open to closed position, and that it is clear of objects which may cause inadvertent operation.
