Abstract

The valve has 2 coaxial control sliders (8,10) within a slider bore (52), for connecting 2 load terminals (A,B) with a pressure space (P) or a feedback space (R), held in an initial position by a spring device (58) with a spring element positioned between the sliders. The spring device has a stop for limiting the maximum working length of the spring element., provided by 2 spring plates mounted on a tension rod.
