When you turn off the control transistor, the solenoid voltage collapses and then reverses by a diode drop as the inductive kick flies back, but the capacitor voltage has to slowly discharge ...

The new valves achieve a compact design thanks to AC08 coil technology that optimises the ratio between the iron circuit and the solenoid coil winding. As a result, the standard version valve ...
