Solenoid valve 2/2-stroke , G3/4", Ms/HNBR, 24VDC 0-10bar, with control, Tmax.=+ 150°C
An electromagnetic valve is an electromechanical device designed to regulate the flow of all types of liquids and gases. It consists of a housing, a solenoid (electromagnet) with a core on which a disc or piston regulating the flow is mounted.
A solenoid (or electromagnetic) valve consists of two main components:
- the solenoid itself has a core that moves inside the solenoid coil;
- a valve that actually regulates the flow with its diaphragm or piston.
The solenoid valves open/close by moving the magnetic core. It slides into the solenoid when an electric current is applied to it. Modern solenoid valves are designed to be as compact as possible, but at the same time sealed and reliable.
According to the principle of operation, electromagnetic valves are divided into two groups: direct and indirect action. The principle of operation of the first is based only on the force of an electromagnet, which must have a very high power. Therefore, there is no specific restriction on the nominal diameter (through hole) of solenoid valves of this type, as well as on the operating pressure in the system where they will be installed. One of the advantages of direct-acting valves is the high frequency of operation, as well as operation in the absence of pressure. The second group, indirect valves, uses the energy of the medium that moves in the system to operate. Such electromagnetic valves have a fairly wide range of nominal diameters and operating pressures. In addition, the solenoid in such a valve usually has less power. Another advantage of these valves is usually the greater smoothness of operation, which protects the entire system from water hammer.
According to the condition without electrical voltage, solenoid valves are divided into normally closed and normally open. The first ones close the passage hole if no electric current is applied to them. The second ones, on the contrary, open the passage hole in the absence of power supply. Therefore, normally closed ones open the passage when current is applied to them, normally open ones close it.
Choosing a solenoid valve is very difficult. After all, the type and characteristics of this unit are influenced by many factors:
- scope of application, type of system;
- the size of the through hole;
- the type of medium that will pass through it (gas, liquid, oil) and the level of its aggressiveness (acidity);
- flow temperature;
- working environment pressure;
- valve type (normally closed or open);
- the method of connecting the valve to the pipes (thread, flange, welding, fitting).
The electromagnetic (solenoid) valve, which was correctly selected and installed, practically does not require special maintenance. The most common malfunction is when the coil or diaphragm fails due to wear or factory defects. In such cases, repairs can be carried out without the need to dismantle the valve, immediately at the place of its installation.
