7032
Non-return valve
Prevents brief movements of the hydraulic cylinder (3084) in the switching process of the solenoid valve (Y145).

Shuttle valve LS signal
7085
Pressure relief valve LS pressure
190 bar
7087
Pressure balance
7087 a) Open from P to T if no consumer is active = Neutral circulation. When a consumer is active, the required flow rate is regulated - the residual volumetric flow is directed to the tank. 7087 b) Regulates the required flow rate to the scraper floor motor if the scraper floor is ON. 7087c) Opened with the function “Scraper floor ON”, in addition to scraper floor ON solenoid valve (Y223), in order to keep resistance low.

Y027
Solenoid coil for opening tailgate
Powered: pressure build-up in the piston space of the tailgate hydraulic cylinder (3018) = open tailgate.
Y028
Solenoid coil for closing tailgate
Powered: pressure build-up in the rod space of the tailgate hydraulic cylinder (3018) = close tailgate.
Y063
Solenoid coil for opening cutting floor
Powered: pressure build-up in the piston space of the cutting floor hydraulic cylinder (3042) = open cutting floor.
Y064
Solenoid coil for closing the cutting floor
Powered: pressure build-up in the rod space of the cutting floor hydraulic cylinder (3042) = close cutting floor.
