How to choose the correct normally open solenoid valve?

Most manufacturers of solenoid valves generally range in price from tens of dollars, tens of dollars, and hundreds of dollars. According to the internal structure, the solenoid valve is divided into core type, recoil type, direct-acting type, pulse type, compound type, double type, self-maintaining type and bistable type. Of course, the price of different models of solenoid valve is also different.

In simple terms, electronically controlled normally open solenoid valve is the use of electromagnetic technology to control the solenoid valve, through the magnetic field to control the movement of the oil pan, open or close the valve connected to various oil pipes, so that the oil pump into the various oil pipes, so that the movement of the oil cylinder becomes more flexible, thus promoting the health of industrial equipment. The scrubber inlet solenoid valve is an industrial device for liquid control based on magnetic field induction, which is an electronic actuator used to control the flow, speed and direction of the liquid. This solenoid valve allows for the desired control and flexibility in operation. According to the various types of solar solenoid valve, it can be divided into various types, relief valve, orientation control, speed regulation type, valve type, etc.

When choosing a solenoid valve, the following four points should be noted.

1. Accuracy and reliability of the shape. The time and rules match. Can the three-position normally open solenoid valve inserted into the solenoid valve accurate and reliable phase change, accurate and reliable correction after disconnection, the smoothness of the whole process, replacement, time of use, etc.

2. What is the frequency of phase change? The frequency of phase change of the solenoid valve per unit of time, on the one hand because it is high, on the other hand, it is better.

3. Tension in the work. The internal leakage of the normally open solenoid valve for liquid is in line with the specification. Working pressure is reduced. In the new plan, the internal leakage is very important, must be serious and careful.

4. The life of the solenoid valve. Solenoid valve is an electric drive, its life depends on the operation and maintenance costs. Of course, good quality requires higher requirements and can be selected according to specific requirements.
