Inlet Section L90LS

AS2 Inlet section for following valve in a flow distribution
system. The load signal from this valve is connected to
the preceding valve. Otherwise, the functionality is as
for inlet section AS except that the section only contains
a load pressure limiting valve, PLM [16].

IP Inlet plate without functions. Contains only connections
for pump, tank and load signal.

Inlet section AS2

CA/CL Combo inlet used as mid-inlet when L90 and K170/
K220 are assembled together. This works as an adapter
plate between valves and replaces inlet sections from
both valves. The combination inlet is available with the
same functionality as the LS2, AS and AS2 inlets. It can
also include pilot pressure supply and the counter pres-
sure function, in which case it replaces the standard,
US [30], and the simpler combined spool and end
section, MU [30], can be used instead. The inlet is
specified in the K170LS or K220LS valve specification,
and the same code (CA/CL) must be entered for item
15.
For more information see the catalogue for K170LS or
K220LS.
