SKIPPER SB (Single Bottom) Sea Valve 100 mm
1. Installation
The SKIPPER SB Sea Valve 100 mm is used for installation of:SKIPPER speed log sensors and Echo
sounder transducers tted with adaptor for XB-100-XX .
Caution!
Be aware that the Sea Valve contains high precision parts and therefore proper
handling when mounting is essential for the nal result.
When handling the Sea Valve, all lifting devices must be attached on the outside of the
valve. It is very important to not insert any chains, wire, rope or any other device into
the valve chamber. This to avoid damaging and any kind of pollution of the Sea Valve.
Caution must be taken when mounting seavalves that all parts are aligned correctly, and that the inside is
clean. DO NOT use liguid sealants, and DO NOT paint the inside of a valve.
The SKIPPER SB Sea Valve 100 mm is delivered partly assembled for transport. The parts necessary for
nal assembly will be found packed in a box delivered with the Sea Valve. First of all, it must be decided
where the Sea Valve should be installed. Normally, this will be in the fore part of the ship, in the centerline,
or as close to the centerline as possible. Optimal system operation is achieved by tting the transducer/
sensor as deep as possible on the hull.
• The active surface of the sensor must be installed with front face a maximum of +/-1 degree to the ships
horizontal plane. (Speed Logs).
• The active surface of the transducer must be installed with front face a maximum of +/-7 degree to the
ships horizontal plane. (Echo Sounder).
Do not mount transducers close to the bow thruster propeller outlets, or aft of other hull installations (outlets,
vents or other protruding details) who may create aeration or turbulence.
It is necessary to select a part of the hull that is submerged and free from turbulence and aeration under all
load and speed conditions, and to avoid positions where air is trapped in heavy weather.
If a at, horizontal section is not available for transducer tting, the shipyard must construct a suitable bed.
Welding seams in this area should be smoothed and rounded off, in order not to create turbulence or aeration
at speed.
Protect the active element of the transducer/sensors during transport and installation, and
do not paint the surface.
The Sea Valve should be placed in a service accessible place, large enough for installation and disassembly
of the sensor unit. See drawing: “Space considerations”.

Important
”Sensors for Speed Log and Echo Sounder are delivered with a xed cable. Attention must be taken
to allow easy replacement/pulling of new cable during maintenance”.
SKIPPER Electronics AS will recommend installation positions if GA-drawings (General
arrangements), lines drawings and frame drawings are made available for study.
Condition.
The welding to hull structures and structural support of the items may be subject to separate approval by
classication societies for each installation on board a ship.
Note: All “Item (X)” references on the following pages, can be found on drawing 100 mm Single Bottom
Ball Valve.

3. Welding the bottom ange
• When the position has been decided, a 220 mm hole is cut in the hull.
• The bottom ange, Item (1), is welded into the hull. Standard welding practice, methods and procedures
should be observed, but may vary. (See welding notes).
Attention:
The bottom ange is a part of the Sea Valve that is machined with high accuracy and it should be
protected after mounting to avoid damage to the bottom ange surfaces. This to avoid leakage. If the
valve is pre-mounted, be sure to protect the valve from being polluted by welding debris.
WELDING NOTES!
All bottom parts and anges for welding are precisely machined parts. During welding of these parts
to the ship’s hull plates, careful attention must be paid to avoid construction strain on the bottom
parts and anges.
• Let parts cool down during welding.
• Over heating may change t and form and result in non-conformity with intended sensor/
transducer.
• Welding to thick hull steel plates will exert high stress on bottom parts and anges.
• Especially care must be taken during welding of stainless steel anges.
• Work must be performed by a qualied and certied welder.

4. Sea Valve Assembly (Orientation not necessary).
Step 1
• Place 1.5 mm gasket, on top of Bottom Flange.
• Then place the Ball Valve element on top of the Bottom Flange. The 16 mm nuts and washers should be
mounted, not tightened.
• Place a 1.5 mm gasket on top of the Ball Valve element.
• Mount the intermediate element on top of the Ball Valve element. The track for o-ring to be upwards.
• All 8 nuts and washers should be mounted, not tightened.
Step 2
• Place the plastic alignment tube, all the way, into the sea valve.
• Tighten 8 nuts ball valve to bottom ange.
• Tighten 8 nuts Intermediate element to ball valve.
• Remove the plastic alignment tool.
Caution must be taken when mounting seavalves that all parts are aligned correctly, and that the inside is
clean. DO NOT use liguid sealants, and DO NOT paint the inside of a valve.

Sensor installation
• Place the O-ring, Item (36) in the groove on
top of the intermediate element, Item (7).
• Apply grease to the O-ring.
• Insert the 2 thread bolts, Item (11) through
the ange and secure with 2 x M16 counter
nuts, Item (28).
• Torque 130 Nm.
• Lower the sensor housing carefully down
to the top of the valve piston.
