Several solenoid coil parameters affect the performance of solenoid valves. These include resistance, Inductance, reactance, Impedance and turns count. Measurement of these parameters may sometimes be needed to predict valve performance (actuating force, response times, power dissipation, size arc suppressors, etc).
Reliability and performance of solenoid valve contribute for its safe operation. Remaining useful life prediction of solenoid valve helps to prevent its failure. Performance of coil insulation is critical for functioning of a solenoid valve. Solenoid valves play a key role in hybrid electric vehicles and industry 4.0.
The resistance will increase with increased coil temperature due to the temperature coefficient of resistance of copper*. The Impedance of the coil is the ratio of the applied AC voltage to the AC current for an AC coil. * Click here for more detail on the resistance of solenoid coils vs temperature.
In the alternating current (AC) operated solenoid valves, the electric current flow through the coil and thus, the resulting magnetic field developed, will vary. This will lead to chatter (oscillation) in the coil. To minimize this chatter, this type of valve employs a shading ring or shading coil .
The solenoid valve customer might sometimes ask for Impedance when he/she really means the Resistance. Coil Resistance is generally specified on drawings or datasheets. The Resistance of the coil (in Ohms) is simply the ratio of the applied DC voltage to the DC current at room temperature (~20°C or 25°C).
The basic working principle of a solenoid valve will follow now. A solenoid is actually an electromagnet wherein a wire coil will be wound around a soft movable ferromagnetic iron core. The core will become magnetized due to the flow of an electric current through the electromagnetic coil. A spring will be attached to the core (armature) .
