Modern pipelines are a very complex technical system, inside which there is a constant movement of significant masses of liquid or gas, and the constantly changing pressure and flow rate sometimes require remote intervention in the work by an automated control system or an operator. The technical means for such regulation is brass solenoid valves . By controlling such valves, it is possible to increase or decrease the throughput of the pipe, or completely block the movement along the pipeline. Solenoid valves have a great reputation for being comfortable and safe to use.
The principle of operation of such valves is quite simple: a special disk, or a piston, can, by extending or moving, arbitrarily change the throughput. All these movements occur under the influence of the solenoid core, that is, an electromagnet. There are many types of valves, which differ in the type of current used, the magnitude of the voltage and the direction of movement of the core.
Regulating solenoid valves are most flexible able to change their operating mode. This feature allows using valves to mix and divide liquid flows, to reduce or increase the flow rate of the working medium. However, the speed of action of such valves is not high enough to urgently stop the pipeline in case of a dangerous situation. In this case, there are so-called shut-off valves that can operate almost instantly.
In many cases, solenoid valves are equipped with a redundant "manual" system. Its use is provided in cases of power supply interruption. They are used today wherever piping and fluid flow control is required.
