HD – Hydraulic control,
pilot-pressure related
(see92080)
▼ Circuit diagram
Stepless adjustment of the pump displacement according
to the pilot pressure.
The control is proportional to the specified pilot pressure
(difference between pilot pressure and case pressure).
Optional:
Control characteristics (HD1, HD2, HD3); pressure control
(HD.B); Remote pressure control (HD.GB);
power control (HD1P)
