Abstract

The hydraulic control system is used for hydraulic actuating cylinders of agricultural or building site vehicles and uses relatively simple valves. The system has group of valves open in rest position and a group of three-way valves blocked in rest position. These valves are actuated by a solenoid and resetting springs. Each valve has a rectangular block shaped body with flow channels and closure elements. Multiple control systems can be built up from these valves.
