1、 The NORGREN solenoid valve is a controller that uses electromagnetic force to control gas or liquid flow. Its working principle is to use the coil on the solenoid valve to generate a magnetic field and control pressure or liquid flow.
The red and white wires on the NORGREN solenoid valve are used for power supply. Among them, the red line is the positive pole and the white line is the negative pole. By connecting the power supply, the solenoid valve can work normally.
2、 The connection method of the red and white wires of the NORGREN solenoid valve
The red and white wires of the NORGREN solenoid valve need to be connected to an external power source in order to function properly. When wiring, the following points should be noted:
1. Connect the red line to the positive pole of the external power supply and the white line to the negative pole of the external power supply so that the solenoid valve can work properly.
2. When wiring, attention should be paid to matching the voltage of the power supply with the rated voltage of the solenoid valve itself, otherwise the solenoid valve may not work properly and may even burn out.
3. Before connecting the power supply, it is necessary to confirm the model and wiring method of the solenoid valve to avoid connecting the wrong wires, which may cause the solenoid valve to malfunction.
3、 Operation steps and precautions
Attention should be paid to the following points when wiring:
1. Firstly, it is necessary to ensure that the input voltage of the power supply matches the rated voltage of the solenoid valve, and do not connect it to the opposite polarity.
2. On the premise of confirming the correct direction of the NORGREN solenoid valve, insert the red line into the positive pole of the power supply and the white line into the negative pole of the power supply.
3. After connection, pay attention to the working condition of the solenoid valve. If it is found that the solenoid valve is not working properly, it may be necessary to check whether the rated voltage and wiring are correct.
4. When maintaining the NORGREN solenoid valve, attention should be paid to whether there are oxidation, aging, and other issues, and it should be replaced in a timely manner.
The connection of the red and white wires of the NORGREN solenoid valve is very simple. As long as it is correctly connected to the power supply, the solenoid valve can work normally. During operation, attention should be paid to the polarity and rated voltage of the power supply to avoid affecting the normal operation of the solenoid valve.
As a common control component, NORGREN solenoid valve has a wide range of applications in industrial automation and home intelligence. Wiring is an important part of the installation and use of solenoid valves. The correct wiring method can ensure the stable operation of the solenoid valve and extend its service life, especially when two wires are connected. This article will focus on the correct connection of the two wires of the solenoid valve.
1、 Basic connection method of two wires for Norgren solenoid valve
The two wires of the Norgren solenoid valve are generally divided into red and black, where red represents the positive pole and black represents the negative pole. Before wiring, it is necessary to confirm the rated voltage of the solenoid valve. Common rated voltages include 12V and 24V. When wiring, the red wire should be connected to the positive pole of the power supply, and the black wire should be connected to the negative pole of the power supply. If it is a DC solenoid valve, it is necessary to ensure that the positive and negative poles of the wiring correspond to the positive and negative poles of the power supply, otherwise the solenoid valve will not work properly.
2、 Correct connection method for 220V AC solenoid valve
Unlike DC solenoid valves, the wiring of 220V AC solenoid valves does not differentiate between positive and negative poles, and only requires connecting two wires to a 220V AC power source. However, it should be noted that when wiring, the power supply should be stable to avoid affecting the normal operation of the solenoid valve due to power fluctuations. In addition, the connection of the grounding wire is also very important, as it can effectively protect the solenoid valve from electric shock damage.
3、 Wiring precautions
1. Before wiring, check the integrity of the NORGREN solenoid valve and power cord to ensure that there are no damages or exposed parts.
2. Choose a suitable power supply based on the rated voltage of the NORGREN solenoid valve to avoid damage to the solenoid valve caused by high or low voltage.
3. When wiring, strictly follow the NORGREN solenoid valve wiring diagram to ensure that each wire is connected to the correct position.
After the wiring is completed, a power on test should be conducted to ensure that the NORGREN solenoid valve can work properly.
4、 Common problem solutions
During the wiring process, it is possible to encounter situations where the Norgren solenoid valve cannot function properly or is unstable. At this point, the first thing to check is whether the wiring is correct, whether there is looseness or poor contact. Secondly, check if the power supply voltage is stable and if the ground wire is properly connected. If the problem still cannot be solved, it is recommended to consult professional solenoid valve maintenance personnel.
