Description of the control of the solenoid valve power supply and accuracy

First, the solenoid valve power supply conditions
1. According to the type of power supply, AC and DC solenoid valves are used respectively. Generally, AC power is convenient to use.
2. Use the AC220V.DC24V as much as possible for the voltage specification.
3. The fluctuation of the power supply voltage is usually +%10%.-15% for AC and ±10% for DC. If it is too poor, it must adopt voltage regulation measures or put forward special order requirements.
4. The rated current and power consumption should be selected according to the power supply capacity. It should be noted that the VA value is higher when the AC starts, and the indirect-lead solenoid valve should be preferred when the capacity is insufficient.
Second, the control accuracy of the solenoid valve
1. The ordinary solenoid valve can only open and close two positions. When the control precision is high and the parameter requirements are stable, please use multiple solenoid valves.
  2. Action time: refers to the completion time of the electric signal being turned on or off to the main valve. Only the patented multi-function solenoid valve of the company can adjust the opening and closing time separately, which can not only meet the control accuracy requirements, but also prevent water hammer damage. .
3. Leakage The value of the leakage given on the sample is the common economic grade. If it is too high, please make a special order.
