Electronic Pressure Control Valves

Electronic Pressure Control Valves (EDS): The electronic pressure control valves convert electrical current into a proportional hydraulic pressure. They are regulated by the electronic control module to activate the hydraulic valves (in the valve body) to the pistons in the clutch assemblies. Two types of EDS valves are used:

EDS with rising characteristic curve




- EDS valves 1, 3 and 6 are identified by a green cap.
- The rising characteristic curve starts at 0 mA = 0 bar, up to 700 mA = 4.6 bar.
- Operating voltage - 12 V
- Resistance at 20 °C = 5.05 Ohm

EDS with falling characteristic curve




- EDS valves 2, 4 and 5 are identified by a black cap.
- The falling characteristic curve starts at 700 mA = 0 bar, up to 0 mA = 4.6 bar.
- Operating voltage - 12 V
- Resistance at 20 °C = 5.05 Ohm
