1. Separate hull flange (3) and flange (4) (with transducer (1) and shaft (5)) from gate valve (2)
by removing hex. Nut (17).
2. Weld hull flange (3) to the hull plate. Confirm that the “FORE” and align marks on the side
of the hull flange face the fore-aft line of the ship within 1 degree. The hull flange should
also be horizontal within 1 degree at ship’s normal trim. Finish the outside hull plate flat with
a grinder.
3. Apply “Kinoruster (Anti-crevice corrosive sealant)” to face A of hull flange ③, both faces of
gasket (18) and flange of gate valve (2).
4. Put gasket (18) onto hull flange (13).
5. Mount gate valve (2), considering the direction of the handle (aft direction normally or
selectable every 45 degrees) so as to allow enough space for operation.
6. Apply “Kinoruster” to face B of flange (4), both faces of gasket (18) and the flange of gate
valve (2).
7. Put gasket (18) onto the flange of gate valve (2).
8. Mount flange (4) (with transducer and shaft) to gate valve.
9. Loosen the hex. socket head bolts (23)and (26), then check that shaft (5) moves upward
