The flexible fuel line shall be pressurised quickly by means of a quick opening solenoid valve, such that one cycle consists of holding the pressure at 1,25 times the nominal working pressure for 10 ± 1 seconds (except for flexible fuel lines with a required material temperature of 120 °C where the hold pressure shall be 1,37 times nominal working pressure) and then reducing it to less than 0,1 times the nominal working pressure for 5 ± 0,5 seconds.

A solenoid valve has two main parts: the solenoid and the valve. The solenoid converts electrical energy into mechanical energy which, in turn, opens or closes the valve mechanically.
