1. General information
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 simultane-
ously, 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.

There are three basic variations of connection blocks:
o Connection blocks with integrated 3-way flow controller, suitable for a constant delivery pump system (open-center) - type PSL
(see sect. 3.1.1)
o Connection blocks suited for a variable displacement pump system (closed center), a constant pressure systems, or if a second
or more separately located directional spool valve banks are fed in parallel - type PSV (see sect 3.1.2)
o Connection blocks for arbitrary supply with pressurized oil either by means of constant delivery pump or variable displacement
pump (external connection) - type PSM (Pos. 3.1.3)
3.1.1 Connection blocks for constant delivery pump systems (with integrated 3- way flow controller) type PSL

Coding for control oil supply table 7
The high control pressure of variable displacement pump controllers may lead to unintentional
movements of consumers with low load pressure even while the respective valve is in its idle
position. The pump gallery is completely blocked with type PSV 5 N to ensure a definitive
separation of pump and consumer circuit. This takes place by means of a solenoid valve. The
LS-gallery together with the LS-controller may be additionally relieved via a separate 2/2-way
directional seated valve.

Standard, with inflow controller, for simultaneous load compensated moving of several consumers (3/3-, 4/3-way spool
valve, standard type)

Without inflow controller intended for singly / successively actuated functions. Additional functions on the consumer
side are not possible. For the max. consumer flow of the indiv. consumer, see table 15 and sect. 6.1 b)

With inflow controller (for symbol, see coding 2) but with reinforced spring at the 2-way flow controller (control
pressure approx. 9 bar). Only usable in conjunction with connection block type PSL.H./... or type PSV with variable
displacement pump / constant pressure system (for note, see sect. 6.1a and b).
