ELECTRO-HYDRAULIC STEERING GEAR
The electrohydraulic steering gear for the Marsili encoding they are called “systems type B”.
The Marsili electrohydraulic gear steering systems 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 piston helm pumps, hydraulic cylinders, electrohydraulic power packs with voltage on demand and accessories.
This allows us to choose the most suitable equipment for each situation, the reliability and comfort are guaranteed.
The Marsili electrohydraulic steering gear systems are designed with an accurate attention to details, during the phases of production and test. All this for the purpose of obtaining systems with high manoeuvrability, maintaining the characteristic smoothness of the hydraulic transmitters during the manoeuvre.
In addition to the manual manoeuvre, an electrohydraulic power pack is installed for a manoeuvre without any effort in NFU ( Non-Follow-Up) or in AP (Autopilot) mode.
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 hydraulic steering systems are made up of one or more hydraulic cylinders, one or more piston helm pumps and one or more power packs.
These are “classic” steering systems since the ‘60s as a concept, but are now produced at a more advanced level both for the design and the material used.
Accessories for the electrohydraulic steering gear systems
To the electrohydraulic steering gear systems, as for the manual steering systems, can be added accessories and components even at a later stage.
- Power packs of the systems Type “B” are classified as “Y” or “W”.
- 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.
- 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.
