Brief description of explosion-proof solenoid valve

Material characteristics:

　　 1. The temperature of the material should be within the allowable range of the solenoid valve of the water heater.

　　 2. The material temperature is not the same as the size of the product, otherwise the electromagnetic coil will be burned, and the hydraulic seal will be aging, which will seriously affect the service life.

　　3. If the substance is a specified commodity circulation, and the counter-current ZDF-N and ZQDF-N are only allowed to be used for dual commodity circulation, please make a special request.

　　4. When the material cleanliness is not high, a recoil filter valve should be added in front of the vacuum solenoid valve. The stainless steel gate valve has a low working pressure and the fashion trend can use a variable distance pulse damper vacuum solenoid valve as a CD machine-P.

　　 5. Material viscosity, usually below 50cSt. Order low-viscosity vacuum solenoid valves for pipe diameters below 15 mm.

　　6. Different types of vacuum solenoid valves are used for quality gas, liquid or mixed conditions.

Natural environment standards:

　　 1. In the natural environment where the air humidity is high and there are water drops in the rain, etc., the anti-drain valve should be used.

　　2. For applications in corrosive or flammable natural environments, priority should be given to choosing corrosion resistance according to the safety factor regulations.

　　3. The high and low temperatures of the natural environment should be within the limits. If there is any deviation, a unique order must be clearly stated.

　　4. Vibrations are often found in the natural environment, the colorful two-color water level gauges are very bumpy and the places where impacts are unique should be selected, such as ship vacuum solenoid valves.

　　5. If the indoor space of natural environment is restricted, please use multi-purpose vacuum solenoid valve, because it saves the bypass and seven manual valves and facilitates online maintenance.

Switching power supply standard:

　　 1. The working voltage specification and model use AC220V.DC24V as a priority.

　　 2. According to the type of power distribution switch power supply, each adopts communication AC and DC vacuum solenoid valves. In general, AC power is easy to access.

　　3. Power supply voltage fluctuations usually use %.-15% for communication and AC, and the allowable DC current is ± up and down. If there is a deviation, a step-down countermeasure or a specific order requirement must be adopted.

　　 4. The rated voltage and loss output power should be selected according to the volume of the switching power supply. It must be noted that the VA value is higher when the communication is started. When the volume is not enough, the indirect guided vacuum solenoid valve should be preferred.
