The HS+ hydraulic steering systems are designed specifically for marine secondary steering applications. They are available with either a 2.5 lpm reversing pump or a number of sizes of PC pump. The systems are protected from rudder strikes by integral relief valves. A solenoid clutch is also fitted so that manual mechanical steering can be used.

Description

The hydraulic steering systems comprise of a compact cylinder which includes the relief valves and solenoid clutch, a reversing or constant running pump, marine hoses, fittings and a reservoir. The system comes filled ready for installation. A choice of pump sizes can be selected with single or twin cylinders to give a range of hard-over times and thrusts.

Application

Designed specifically for the marine autopilot market, they can be used on sailboats and power-craft with displacement and fast planing hulls. The pumps and cylinders can be matched to give the hard-over times and thrusts to suit the application.

Rudder Feedback Sensor

A rudder position sensor can be specified for the HS+50 range.
The typical output signal is 0 to +5V, compatible with most autopilots.
