Item Description
1. Low Current
2. Low Exhaust
3. SF Circuit Fluid (Supply)
4. High Pressure Output
5. High Current
6. High Exhaust
7. SF Circuit Fluid (Supply)
8. Low Pressure Output

Normally high solenoids provide pressure inversely-proportional to supplied current. Normally high solenoids provide full output of pressure with low or no current (50 mA) and very low pressure with high current (850 mA). The LPC solenoid is a normally high solenoid so if power is lost to the solenoid the pressure is at full output.
