General
The directional spool valves types PSL and PSV serve to control both, the direction of movement and the load
independent, stepless velocity of the hydraulic consumers. In this way several consumers may be moved simultaneously, independently from each other at different velocity and pressure ratings, as long as the sum of the partial flows needed for this is within the total delivery supplied by the pump. The proportional spool valves of this pamphlet are designed as valve banks and consist of three functional groups:
