1303948 DAF solenoid valve

  The Solenoid valve is based on the temperature and pressure of the flowing medium, such as the pressure in the pipeline and the no pressure in the self-flowing state. Solenoid valves work differently. For example, if zero-voltage start is required in the self-flow state, the coil will completely suck up the gate body after power is applied.

  Truck above the Solenoid Valve, generally electric side valve are carried out with two lines, constitute one is PWM duty cycle signal, one is long power supply, solenoid valve control type has control positive electrode, PWM signal, there is also control negative pole PWM signal, solenoid valve according to the engine computer provided by different duty cycle signals, open solenoid valve opening is not the same, the larger the solenoid valve duty cycle, the greater the opening of the opening, in this way, the solenoid valve will work longer, the smaller the duty cycle of the solenoid valve, then, The shorter the solenoid valve works per unit of time.
