In neutal position, the valves cross section are as follows:
E_I ≥ 20% of nominal cross section.
E_S ≥ 2% of nominal cross section.
The sandwich plate design directional valve elements L8_ P5... are compact direct hydraulic operated valves which control the start, the stop and the direction of the oil flow. These elements basically consist of a stackable housing (1) with a control spool (2), two hydraulic operating blocks (5), and two return springs (4).
The hydraulic pressure in one of the blocks (5) pushes the control spool (2) from its neutral-central position “0” to the required end position “a” or “b”, and the required flow from P to A (with B to T), or P to B (with A to T) is achieved. When pressure is removed from either one of blocks (5), the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool returns in its neutral-central position “0”.

The performance curves are measured with flow going across and coming back, like P>A and B>T, with symmetrical flow areas and with back-pressure in T ≤ 10 bar (145 psi).
