Requirements for temperature and humidity of solenoid valve during operation

Requirements for temperature and humidity of solenoid valve during operation


Many solenoid valves are universal. Generally, solenoid valves are not waterproof, so necessary choices should be made for the installation environment. Stainless steel products should be selected for corrosive media; There are two types of solenoid valves: normally closed and normally open. Normally closed type means on-power and off-power; Otherwise, normally open type, can be selected according to process requirements and safety. In order to make the solenoid valve work reliably, the environmental conditions for its installation on site are also very important. For example, the maximum temperature cannot exceed the nameplate of the solenoid valve. If the service temperature of the solenoid valve is too high, the service life of the solenoid valve will decrease. If the ambient temperature is too low, it will cause frost on the shell of the solenoid valve, which will cause problems such as sealing filler and make the solenoid valve unable to work normally.


Relative humidity will affect the electrical insulation. Humid environment will reduce the electrical insulation and affect the reliability of electromagnetic valve. Humidity is too high, at a certain temperature, it is easy to cause mold, etc. When there are dust, water droplets, salt fog and corrosive atmosphere in the use environment, the influence of them on the solenoid valve should be considered. Products with good sealing performance should be selected, such as waterproof, splash-proof and dust-proof solenoid valves. When the use environment requires explosion-proof, explosion-proof solenoid valve should be selected. Vibration-Resistant Solenoid valve should be selected in the environment with vibration and impact. In addition to the correct selection of solenoid valves for the above environment, certain Protection Measure should be taken to protect the solenoid valves.
