Following table is control terminal and solenoid valve state relation table
| The terminal title | Control terminal I | Control terminal II | The solenoid valve previous condition | The solenoid valve new state |
| Control wave | Low level pulse | High level pulse | Open (or closing) | Constant |
| Close (or opening) | Open (or closing) | |||
| Low level pulse | Low level pulse | Close (or opening) | Constant | |
| Open (or closing) | Close (or opening) | |||
| High level pulse | Low level pulse | Any state | Constant | |
| High level pulse | High level pulse | Any state | Constant |
Wherein, be high level under control terminal I and the control terminal II normal state.
When control terminal I received high impulse, control terminal II is akinesias of solenoid valve under any state, and when control terminal I and control terminal II all receive low pulse, solenoid valve will close to state as shown in Figure 2, can remain unchanged as closing then.
When control terminal I receives low level pulse, when control terminal II receives high level pulse, 1 pin of electromagnetic valve coil 6 is a high level, 2 pin are low level, moving iron core 10 produces magnetic under the effect of electromagnetic field, its upper end is opposite with the permanent magnetic field lower end polarity of permanent magnet 8, both inhale mutually, moving iron core 10 is by the upper end of adhesive to spool 7, originally the valve that was in closed condition will be opened, and that has opened then can remain unchanged, and the outage back is because the permanent magnetism of permanent magnet 8 is made every effort to overcome the elastic force of having obeyed spring 9, moving iron core 10 still keeps and spool 7 upper end adhesives, and valve keeps opening constant.
When control terminal I and control terminal II receive the low level pulse signal simultaneously, bidirectional triode thyristor BCR and the equal conducting of bidirectional triode thyristor BCR2, the relay J adhesive, it is high level that the electric power polarity of coil 6 is changed into 2 pin, 1 pin is a low level, the permanent magnetic field lower end polar repulsion of moving iron core 10 upper ends and permanent magnet 8, moving iron core 10 is under magnetic force and spring force acting in conjunction, make the valve closing of opening originally, originally the valve that was in closed condition will remain unchanged, outage back is because spool 7 is far away with moving iron core 10 distances, and the permanent magnetic field that permanent magnet 8 produces is far smaller than the thrust of spring 9 to the suction of moving iron core 10, and valve will keep closed condition.
