How to Choose a Normally Open Solenoid Valve Correctly?

Most solenoid valve manufacturers generally have prices ranging from several tens of yuan to several hundred yuan. According to differences in internal structure, solenoid valves are divided into pilot type, back-flush type, direct-acting type, pulse type, composite type, double type, self-maintaining type, and bistable type. Of course, the prices of different models of solenoid valves are also different.

In simple terms, an electrically controlled normally open solenoid valve uses electromagnetic technology to control the solenoid valve. Through a magnetic field it controls the movement of the oil pan, opening or closing the valves connected to various oil pipes, letting the oil pump enter each oil pipe, making the action of the oil cylinder more flexible, thereby promoting the health of industrial equipment. A floor scrubber inlet solenoid valve is an industrial device that performs liquid control based on magnetic field induction; it is an electronic actuator used to control liquid flow rate, speed, and direction. This solenoid valve can achieve the expected control and operate flexibly. According to various types of solar solenoid valves, it can be divided into various types, overflow valves, directional control, speed regulation types, valve types, and so on.

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

1. Accurate and reliable shape. The time conforms to the rule. Whether a 3-position normally open solenoid valve can accurately and reliably perform phase change after insertion, accurate and reliable correction after disconnection, smooth throughout the whole process, replacement, and the time of use, and so on.

2. What is the frequency of phase change? The phase change frequency of the solenoid valve per unit time: on the one hand, the higher the frequency, the better its performance.

3. The tightness during work. The internal leakage of a liquid-use normally open solenoid valve conforms to the specifications. The working pressure is reduced. In a new plan, internal leakage is very important, and one must be serious and careful.

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