HMU-01 are pressure relief valves in
modular execution with ISO4401 size 06
mounting surface, specific for fine pressu-
re control at low flow.
They are mainly used for piloting lines and
as pilot stage for AGAM and ARAM pres-
sure relief valves.
RR-3/* are 2 way pressure reducing val-
ves in modular execution with
ISO4401size 06 mounting surface, speci-
fic for piloting lines.
The reduced pressure has a fixed setting
correspondent to the load value of the
regulation spring.
The standard setting is 30 bar, available
optional settings 7, 14, 24 bar
They are mainly used on DPZO proportio-
nal valves to ensure a stable reduced
pressure to the pilot valve.
HC-031/8 is a 3 way pressure compensa-
tor in modular execution with ISO4401,
size 06 mounting surface.
When assembled with directional propor-
tional valves, it provides a constant pres-
sure drop = 8 bar (fixed setting) across
the lines P-A or P-B
In this way the flow controlled by the pro-
portional valve is independent to the load
variations at the user ports.
They are mainly used in sky lift for the
basket levelling control.
HJ-012 is a modular plate with
ISO4401size 06 mounting surface, predi-
sposed for the installation on A and B
lines of cartridge valves type JO-DL-4-2
(see KT, tab. E115)
In modular combination with directional
valves they are used to intercept the A
and B user lines and thus prevent the
undesired movement of the actuator.
