3-Way-Switch Logic Valve

The hydraulic 3-way-switch is a logic valve which works automatically. It solves with little energy the problems of long hydraulics pipe lines, works as a return flow relief or as a rapid traverse valve. In the usage of hydraulics the 3-way-switch is also called 3/2-way-switch, however without any external operating units. Shown is the simple construction including a few components. The automatical control can be clearly seen and the two switching positions will always be attained.
