2.2 WELDED-TO-HULL-FITTING WITH VALVE TYPE 48.1.RVI WITH 48.1RVB. 16
SENSOR OR 65.1.RVI WITH 65.2.RVB.20 SENSOR
(Drawing n° D0343)
Drill a 77 mm diameter hole in the hull for 48 sensors and a 92 mm diameter hole for 65.2 sensors. Do
an external chamfer of 5 mm (45°) for welding.
Prior to weld in the hull casing (1) the hull fitting is to be fully dismantled and O-rings are to be
taken off.
1. Hull-casing (1) must be properly positioned, follow suggested procedure on drawing C1287. Weld
the hull-fitting to the hull. After three or four spots have been welded on the internal side of the
hull, remove the tools. Check that the lower part of hull-casing (1) does not protrude the hull, and
grind the external seam flush with the hull.
IMPORTANT: Hull-fitting mechanical tolerances are very precise. In order to avoid any
possible damage, do not heat the hull-fitting when welding it.
2. Weld piece ref (2) on hull-casing (1).
3. Weld the four try-bolts (3) on lower flange (2) - might already be done in factory -
4. Clean and oil up bearing surface of 0-ring (11) and (12). Put them in place. Install and position the
gate valve (4).
5. Put 0-ring (6) and position upper flange (5).
6. Screw nuts (19) - do not forget the washers (18) - on the thru-bolts (3).
7. Put the lower 0-ring seal ref (13) in place.
Fill the inner part of the outer bush ref (16) with self polymerizing silicone rubber. Be careful to
not over fill. Force the isolating part inside and clips it. Check positioning of hull-casing and also
check that nothing protrudes inside by carefully introducing the sensor. Let the paste harden the
time required.
8. Put flat seal (7) in place. Carefully lubricate the sensor and introduce it. Use grease supplied with
spares.
9. When properly positioned, the sensitive surface of the sensor protrudes at least 1 mm from external
bush, and the red mark on the head is directed towards the bow.
10. Fix sensor flange (8) with screws (9) and washers (20); put circlip 15.
11. Connect the link (10). Check link length: it must be long enough to allow closing of the valve and
short enough to prevent sensor from escaping and passing over 0-ring (6).
To avoid sensor damage, it is recommended to put sensor in place just before departure, or while at sea
(in this case, do not forget to close the valve). When using anti-fouling paint.
DO NOT PAINT THE ELECTRODES - DO NOT GREASE THE ELECTRODES
