Principle
Electric steering system is equl with the power steering system equipped a solenoid valve.
It is the system which steers with solenoid valve by comparing resistance values of electric handle and rudder angle sensor
It consists of a cylinder and a pump, an solenoid valve and a electric handle.
The cylinder makes the rudder move and the pump supplies the oil to the cylinder. Handle is to swap the direction of hydraulic pressure
Cylinder is classified Single, Rotary, Twin, Two rudders by torque and appearance
Pump is classified Pulley type drived by engine and Power unit drived by electric motor
We offer 7 kinds of handles with various appearance and functions.
You can choose the combination fit to your vessel
Key features
Narrow handle diameter helps you operate with small energy and power steering system offers light operation
The number of rotation wheel is 2.8 like the hydraulic handle
Analogue type of a indicator for handle and a rudder angle indicator are applied.
Controlled by Joystick / Autopilot
USB port
Autopilot can be used together.
Application
Vessel above 350HP
A wide range of vessel from fishing boat to ferry
Principal
Power steering system consists of a cylinder, a pump and handle. The oil is pressured from hydraulic pump and a
handle(orbitrol) control a cylinder.
The cylinder helps rudder move and the required oil is supplied from the hydraulic pump.
Cylinder is classified Single, Rotary, Twin, Two rudders by torque and appearance
Pump is classified Pulley type drived by engine and Power unit drived by electric motor
We offer 7 kinds of handles with various appearance and functions.

Class
Principal
The manual steering system is the device that a helm pump driven by the rotation of the steering wheel supplies oil to the cylinder and pushes the piston of the cylinder to have the rudder shaft move.
It is a simple system consisting of a helm pump and a cylinder.
Cylinder has 4 types of single, rotary, twin, and two rudder.
D-I offers the best options to combine kinds of help pumps and cylinders.
Our choice mostly satisfies customers, but in case of your special needs, you have many optional ways.
The number of rotation wheels is defined by the capacity of the cylinder and the helm pump (cc/rev).
You can select the specification you want.
Key features

2 helm pumpsâ??below 50cc, above 50cc
Compatible with commercial handles in the range of 300 mm to 1,500 mm
Dual handle installation is possible.
The lock valve is supplied as default, which can fix the rudder where the handle stops.
Structure that the rudder does not rotate even when the tide powers the rudder
Rudder angle indicator attachable
Application
Suitable for vessels below 500 HP
A range of vessels from leisure ships, fishing boats, commercial boats, and passenger boats
