Note: The gate valve requires service space of 700 mm. For details, see the installa-
tion drawing at the back of this manual.
1. Unfasten M16 nut (3) and spring
washer (11) from the assembled
gate valve to remove the follow-
ing five items.
1) Gate valve (20)
2) flange (3)
3) Gasket 1 (18)
4) Gasket 2 (18)
5) Shaft assy.
2. Set the flange (3) to the mount-
ing location.
The "FORE-AFT" line on the
spacer must be parallel with the
ship's fore and aft line (within
1°). For horizontal direction, the
bottom of the spacer must be parallel with the ship's draft.
Note: Handle the top side of the flange (3) carefully to preserve the waterproofing.
3. Weld the flange (3) to the ship's hull. The welding and doubling methods are left
up to the shipyard.
