GF27.60-P-3017AHX Control Valve Pressure, Function
TRANSMISSION 722.930 up to 31.5.11, 722.931 as of 1.6.11
in MODEL 212.0/ 2

Function requirements for control valve pressure, general
^ Status "Circuit 87 ON"
^ Circuit 61 ON

Control valve pressure, general
The control valve supply pressure is drawn from the working pressure and is limited to a maximum pressure of 8 bar.
2 supply pressure regulating valves are used.
^ Supply pressure regulating valve 1
^ Supply pressure regulating valve 2

Supply pressure regulating valve 1
Supply pressure regulating valve 1 supplies the following control solenoid valves:
- Working pressure control solenoid valve (Y3/8y1)
- Clutch control solenoid valve K2 (Y3/8y3)
- Multidisk brake control solenoid valve B2 (Y3/8y6)
- Wet clutch control solenoid valve (Y3/8y9)

Supply pressure regulating valve 2
Supply pressure regulating valve 2 supplies the following control solenoid valves:
- Clutch control solenoid valve K1 (Y3/8y2)
- Clutch control solenoid valve K3 (Y3/8y4)
- Multidisk brake control solenoid valve B1 (Y3/8y5)
- Multidisk brake control solenoid valve B3 (Y3/8y7)

Using 2 supply pressure regulating valves means that the control solenoid valve groups are isolated from each other and when no gear is shifted a reciprocal influencing of the control solenoid valve groups occurs.
