ABSTRACT:
A hydraulic valve device for controlling a double action, piston-type servomotor adaptable for steering a self-propelled agricultural vehicle and including a pair of identical interconnected valve groups, with each group connected to an opposite side of the servomotor and further connected to a source of pressurized fluid and an exhaust outlet, whereby selective actuation of the hydraulic device creates a pressure difference in a servomotor forcing the piston to move in a predetermined direction.
