ABSTRACT:
A steering control valve system for a crawler vehicle has four valve spool bores formed in parallel to each other at equal intervals in a valve body, four valve spools respectively inserted slidably into the four valve bores, four actuator members respectively inserted slidably into the four valve bores so as to respectively actuate the four valve spools, and a link mechanism for operatively connecting between the four actuator members and operating mediators, wherein the valve system is controlled by only a push-in operation of the valve spools. The operating mediators are steering levers and a brake pedal or electric motors and operating buttons.
