Solenoid valve coils are electromagnetic devices designed to efficiently transform electrical power into lateral motion. They convert electrical power to a magnetic field, which is then utilised to activate the valve and manage the flow of various fluids (liquid, air, gas). These coils are usually made using copper wire wound around a hollow tube, producing a magnetic field when electric energy flows through it.
Furthermore, when the solenoid valve coil is placed over a ferromagnetic core, often composed of 430F stainless steel, the resulting magnetic field drives the plunger deeper into the coil. This motion creates an opening that manages the direct-acting valve, among other things. Solenoid valve coils are available in different sizes, voltages, IP protection, temperature, and power ratings.
How Do Solenoid Valve Coils Functions?
A solenoid coil is composed of a copper wire, wound around a hollow core or bobbin. When an electric current passes through the wire, it produces a magnetic field inside the core. Here’s how solenoid valve coils work:
- Plunger/Armature: Within the core is a mobile ferromagnetic device known as a plunger or armature.
- Valve Actuation: When the coil is powered, the magnetic field draws the plunger, moving it within the core. This movement is then used to open or close the valve, efficiently regulating the flow of fluid.
- De-energising: When the current is turned off, the magnetic field falls, and a spring (or sometimes gravity) takes the plunger to its previous (original) position, closing or opening the valve.
