WARNING! Port X pressurization with D2 controller!
Port X of D2 controllers is a measuring port only. External pressurization leads
to an impermissible pressure increase and can cause serious injury or death,
or can cause damage to the axial piston unit.
▶ Make sure that no external pressure is applied at port X�
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
female threads and should not be exceeded. For values, see Table 10.
• Threaded plugs:
For the metallic threaded plugs supplied with the axial piston unit, the required
tightening torques of threaded plugs M
• Mounting bolts:
For mounting bolts with metric ISO threads according to DIN 13 and/or
ASME B1.1 threads, we recommend checking the tightening torque in individual
cases in accordance with VDI 2230.
In addition to the ports specified in Table 9 "Ports A15VO/A15VLO series 12"
on page 38, axial piston units may have openings that are also closed with
a threaded plug. These plugs must not be opened on the customer side.
If you have opened the threaded plug accidentally, please contact your local
contact person to ensure safe re-closing of the plug. You can find the address at
