The gas solenoid valve is normally closed when the power is off

The gas solenoid valve can be regarded as a relatively general gate valve. From the surface level, the more remarkable characteristics of the gas solenoid valve are promoted by the switching power supply. But the specific gas solenoid valve has the same characteristics that are very different from other relays, that is, when the power is not plugged in, the gas solenoid valve will generally be in a normally closed condition.
According to the difference of opening and closing under power failure, the gas solenoid valve is divided into normally open type and normally closed type. Because the latter is more common, it is written above that most of the gas solenoid valves are normally closed when the power is off. The benefit of opening and closing depends on whether it is plugged in or not, the material can be opened according to the gate valve without the customer's active opening, which is very convenient. The benefit of normally closed depends on the customer's active and actual operation, the gas solenoid valve will be opened to let the material basis, the safety factor of doing so will be much higher. In the middle of safety and convenience, most people choose safety, so the obvious characteristic of the gas solenoid valve is that it is normally closed when the power is off.
1. Environmental sanitation type connection, that is, pipe hoop type connection, this method is connected with idf supporting parts, which can be quickly installed and disassembled, and is convenient for normal cleaning work.
2. Flange connection method. Most of the externally threaded magnetic flip-column level gauges are used in the pharmaceutical, food and other industrial production and the introduction of pharmaceutical preparations. The flange-connected magnetic flip-column level gauge is also used to accurately measure the total flow of crude oil, geological surveys, and concrete slurry.
3. Flange connection is the most commonly used and long-standing magnetic turning column level gauge at this stage. The isolated anti-corrosion solenoid valve is equipped with connecting flanges on both sides of the flange magnetic turning column level gauge sensor. The fixed raw material between pipeline flanges is anchor bolts, and some installation methods are unilateral.
