STEERING GEAR WITH ORBITROL

For the MARSILI encoding they are called “systems type F”.

The MARSILI servo assisted steering gears meet perfectly the needs of motorized vessels of all types from nautical to working ones.

Very simple to install and built with materials which are resistant to the maritime environment.

A large range of orbitrols, hydraulic cylinders, electrohydraulic power packs with voltage on demand and accessories, allow a precise choice of the most suitable equipment for each situation, the reliability and comfort are guaranteed.

The MARSILI servo assisted steering systems are designed with an accurate attention to details, during the phases of production and test, aiming to obtain systems with high manoeuvrability.

The main manoeuvre in the systems type “F” is made by means of an orbitrol (assisted manoeuvre) with a steering wheel, with no effort needed.

The orbitrol is powered by the power pack, to which the solenoid valves can be added to connect a joystick or an autopilot.

The MARSILI power packs are adaptable to all kinds of autopilots.

The standard directional valves are 12V or 24V ON-OFF, but proportional directional valves can be supplied as well.

Usually, the servo assisted steering systems are made up of one or more hydraulic cylinders, one or more orbitrols and one or more power packs.

These are “classic” steering systems since the ‘70s as a concept, but are now produced at a more advanced level both for the design and the material used.

To the servo assisted steering systems, as for the electrohydraulic steering systems, can be added accessories and components even at a later stage.

The power packs of the servo assisted systems are classified as “Y” or “W”.

The power packs type “Y” exploit the power of an electric motor coupled to a gear pump, the tank and the base of the electric motor are complete of control and safety valves and filters; the movement of the rudder is obtained by means of a solenoid valve controlled by an electric transmitter on the bridge.

The power packs type “W” exploit the power of a gear pump coupled to a motor on board or to a belt driven support which transmits the rotation and, thus, the oil flow to the valve group installed on the tank.
