Electro-Hydraulic Piston Type Steering Gear

Use the open circuit which solenoid valve or electro-hydraulic valve can control. It set with two independent AC motor pump units (add one DC motor pump unit in torrent area), the two motor pump units work alternative. Through the two piston type cylinders push the tiller and rotate the rudder to attain the purpose of controlling the ship’s course.
Feature : Compact in structure, convenient in arrange of rudder driving unit, the integrated pump and valve units cut down the installation and maintenance cost
Application: Can be used in all kinds of vessel, especially the vessel which have requirements for the weight and dimension of the steering gear.
Certificate : CCS, BV, ABS, GL, NK,mill certificate etc
Country of Origin : CHINA
