Detailed Information
The ML+40 combines a hydraulic cylinder, pump, IP67 motor, clutch and reservoir in one powerful and compact unit. To operate the clutch is engaged and the cylinder extends and retracts by means of reversing the motor polarity. Integral relief valves protect the unit and its mounting from rudder strikes etc. and anti-cavitation valves are also incorporated to allow full stroke speeds of up to 2 seconds when back-driven by the helm.
Designed for ease of servicing with a motor that can be removed from the unit without affecting the hydraulic circuit.
A full range of spares, seal kits and servicing tools are available.
The ML+40 is supplied pre-filled and ready to install.
Application
Ruggedly designed specifically for the marine autopilot market where they are widely used on sailboats and power craft with displacement or fast planing hulls. They are ideal where space is limited as there is no separate pipe-work or reservoirs to fit.
The unit can be mounted in any attitude.
