Description
This unit is a direct acting, screw-in cartridge style,
spool type, hydraulic 3-way directional control ele-
ment, requiring remote pilot actuation. This valve
allows ow from port 3 to port 2 with a spring bia-
sed spool. Port 4 is blocked. The spool will shift when
piloted at port 1 with sucient pressure to overcome
the spring bias and allow ow from port 3 to port 4.
Spring is vented to port 4. This valve shifts in an open
center position.

Installation information
ATTENTION!
Only qualied personnel with mechanical
skills may carry out any maintenance work.
Generally, the only work that should ever be
undertaken is to check, and possibly replace,
the seals. When changing seals, oil or grease
the new seals thoroughly before tting them.
NOTE!
1) When tting the screw-in cartridge valve,
use the specied tightening torque. The value
can be found in the chapter "Technical data".
NOTE!
The seals are not available individual-
ly. The seal kit order number can be
found in the chapter "Technical data".
