Hydraulic Installation
Fin Valve Unit
The Fin valve unit should be located as close as possible(Recommended < 2,5m (max 3,5m)), to the Actuator Valve Unit with recommended hose
dimensions (System drawings). Use a minimum 2 layer steel braided hoses.
If the fi n valve unit is installed more than 2,5m from the actuator, very stiff (none expanding) hoses or even better, some of the distance in rigid piping
is necessary to not make the fi n movement “soft” by the hoses expanding with varying pressure. Always fi t hoses to the hull on soft mounts.
The unit must be mounted on a rigid flat surface - and we recommend to use a vibration dampening material behind them to avoid any high-frequency
noise/vibration to go into the structure of the boat.

IMPORTANT
Manual decouple valves have to be fully closed during normal operation of the stabilizer system.
WARNING
If the valve is unlocked and opened be aware of unexpected movement of fi ns and cylinders. Especially if the boat is afloat.
