Why Solenoid Coils on Hydraulic Valves Burn-Out | Power ...

2015-3-10 · The short answer to this is: the solenoid coil will fail and therefore the hydraulic valve itself will cease to function. In AC electric coils the resistance or impedance of the coil is lowest when the solenoid is open, i.e. when the plunger is out. Impedance increases as the plunger is pulled into the closed position.
