1) The measuring system and thread size can be found in the installation drawing.
2)
Momentary pressure peaks may occur depending on the application. Keep this in mind when
selecting measuring devices and fittings.
3) O = Must be connected (plugged when delivered)
X = Plugged (in normal operation)
4) Plugged for external boost pressure supply (size 28 to 63).

must be connected (see chapter 7.3 “Installation
position” on page 31)
6) For size 28 and 45, port G serves as “boost pressure port inlet F
a
” and must be connected for
filtration in the pressure line.
7) Only available on version with pressure cut-off.

The following tightening torques apply:
• Fittings:
Observe the manufacturer's specifications regarding the tightening torques of the
fittings used.
• Female threads in the axial piston unit:
The max. permissible tightening torques M
G max
are the maximum values for the
female threads and should not be exceeded. For values, see Table 11.
• Threaded plugs:
For the metallic threaded plugs supplied with the axial piston unit, the required
tightening torques of threaded plugs
M
V
apply. For values, see Table 11.
• Mounting bolts:
For mounting bolts with DIN 13 metric ISO threads or ASME B1.1 threads, we
recommend checking the tightening torque in individual cases in accordance with
VDI 2230.
