Modular cartridge valves type LIM, LIR, LIC
Pressure controls: relief, reducing, compensator, ISO 7368 size from 16 to 80
LIM, LIR and LIC are pressure control
valves composed by a 2-way cartridge
housed in a standard recess and by a
functional “cover" ቢ.
The cartridge is composed by a poppet
ባ hydraulically piloted by means of
internal connections in the cover (X, F,
Y) and sliding into a drilled sleeve ቤ;
cracking pressure value depends on
poppet spring ብ.
Pressure relief valve ቦ with manual setting is housed in the cover for sizes 16,
25 and 32 and is mounted on the cover
for sizes 40…80.
Poppets may have different geometrical
shapes and area ratios as described in
section ‫ ݛ‬to optimize the control.
These valves are available in standard
sizes 16 to 80 according to ISO 7368
(DIN 24342).

Cover according to ISO 7368
MM = pressure relief control with manual setting;
MHA= pressure relief control with solenoid valve for venting. Unloading when solenoid is deenergized;
MHC= pressure relief control with solenoid valve for
venting. Unloading when solenoid is energized;
RA = pressure reducing control with manual
setting. Open in resting position;
C
= pressure compensator to be coupled with
flow control valves;
CM = pressure compensator with mechanical max
pressure regulation to be coupled with flow
control valves.

Seals material:
omit for NBR (mineral oil & water glycol)
PE = FPM
Series number
Voltage code (only for LIMH*), see section ‫ݟ‬
00 = valve without coils (only for OI solenoid)
Only for LIMH*
X = without connector
See section ‫ ݟ‬for available connectors, to be ordered separately

Size: 1 = 16;
2 = 25;
3 = 32;
4 = 40;
5 = 50;
6 = 63;
8 = 80
LIRA is available only in size 16, 25, 32, 40
Pressure range:
50 = 6 ÷ 50 bar;
100 = 8 ÷ 100 bar;

210 = 10 ÷ 210 bar;
350 = 15 ÷ 350 bar

Pilot valve (only for LIMH*):
-I = DHI for AC and DC supply, with CURUS certified solenoids
-E = DHE for AC and DC supply, high performances
-ER = DHER as DHE but with CURUS certified solenoids
Options: see section ‫ݝ‬
