Although the solenoid directional control valve is a device with a simple construction, its use is the cause of many problems. Installing a solenoid valve is a brilliant solution, but also difficult to understand and requiring a lot of knowledge to use it. Even more so, it is not surprising that there are a lot of solutions available on the market and even more valves, which are controlled by an electromagnet.
The solenoid valves are very different from those manually operated or remote hydraulic valves. The solenoid directional control valve is electrically controlled and perfectly replaces all large, complicated hydraulic systems. The directional control valve is also much easier to mount, which further reduces its cost.
The electromagnet consists of a winding wound on a plastic, ceramic or brass casing, placed in an iron casing with an iron spindle. The casing is a yoke that absorbs the magnetic field induced by the current flowing in the coil. The movable iron rod closes the field. The coil can also serve as a spindle bearing. As the air gap between the stem and the yoke diminishes, the magnetic field strength in the core increases, and with it the force exerted by the stem on the load. When the spindle is completely submerged in the coil, both ends of the mandrel close the air gaps.
Control is a very important element. The choice of controlling our solenoid is even more important. An incompetently chosen solution can cause us more problems than we can imagine. It is also worth paying attention to the appropriate voltage value.
Throughout the valve we find one or two electromagnets. After activating the electromagnet, its jumper moves the slider in a given direction by executing a specific wiring diagram. More complicated valves also have a vent hole.
Before installing the electromagnet in your machine, it is worth carefully read into the documentation regarding all the solutions used in the purchased model. Valves can be diametrically different and you can easily spend your money in the mud. Much worse than buying a bad valve will be inability to handle it. Electromagnetic control requires knowledge about the entire process, in particular when the magnet is to be switched on and off several times within a seconds.
