DYA Piston Fork hydraulic steering gear
The fork-shifting rudder-pushing device is makeing the pistion do the reciprocating movements in the cylinder, then through the fork-typr tilller output the rudder torque. The cylinder we adopted to use V-type rudder sealing ring. This rudder-pushing device has features of simple structure, reliable operation, easy maintenance and well output torque.
