1. Please indicate the model, nominal diameter, nominal pressure, working medium, working pressure difference, medium temperature, power supply voltage and frequency, and medium viscosity when ordering.
2. The general operating voltage of the solenoid valve is 220V, and the voltage fluctuation is 85%~110% of the rated voltage. If it exceeds this range, please indicate the voltage fluctuation when ordering. Other specifications of power supply voltage can be specially ordered.
3. The opening time of the valve is more than 12 hours/day, please use the normally open solenoid valve. When there are flammable and explosive products around the environment, please use explosion-proof solenoid valve.
