Electrically operated solenoid valve.
Technical data
| Connection |
| Pin No. | Signal type | Description |
| 1 | Control voltage | The STC control module activates each valve by feeding pin 1 with B+ |
| 2 | Ground | All the valves are grounded through pin 25 on the STC control module |
The valve is grounded on pin 2 and is activated by the STC control module putting B+ on pin 1.
Every valve has three connections.
| • |
Oil pump output pressure
|
|
| • |
Oil pressure to the hydraulic cylinder
|
|
| • |
Oil return to the reservoir
|
|
The valves have two positions: "Active" and "Inactive".
When a valve is active the pump output is connected to the cylinder . When a valve is inactive the pump output is connected to the return line to the reservoir.
