Mechatronic Solenoid Valves (MV), Electronic Pressure Control Valves (EDS)

Mechatronic Solenoid Valves (MV), Electronic Pressure Control Valves (EDS)

The Mechatronic (electronic module and hydraulic control unit) has various solenoid valves and electronic pressure control valves.

Brief description of components (solenoid valves)
The solenoid valves are 3/2-way valves, i.e. valves with 3 connections and 2 switch positions.

Brief description of components (electronic pressure actuators)
The electronic pressure actuators convert electric current into a proportional hydraulic pressure and thus activate hydraulic valves with their corresponding switch elements.

Three types of EDS are fitted:
- EDS with rising characteristic curve (orange cap)
Pressure range 0 to 4.7 bar
Power supply 12 Volts
Resistance 5.05 Ohm (at 20 °C)
- EDS with rising characteristic curve (yellow cap)
Pressure range 0 to 4.6 bar
Power supply 12 Volts
Resistance 5.05 Ohm (at 20 °C)
- EDS with falling characteristic curve (blue cap)
Pressure range 4.6 to 0 bar
Power supply 12 Volts
Resistance 5.05 Ohm (at 20 °C)

Diagnosis instruction
Before replacing the mechatronics or gearbox, run the following service function:
