How The Solenoid Principle Is Used in Hydraulics and Pneumatics

Solenoid valve working principle works something like this; it is basically a coil of wire which is utilized as an electromagnet. It is a device which is widely used to convert electrical energy into mechanical energy – Solenoid valve. The valve creates electric current from the magnetic field to generate linear motion.

The solenoid valve is majorly used in electrical devices like switches, liquid circuits, washing machines, dental equipment, irrigation systems, car wash systems, sprinkler systems as well as automobiles.

How Solenoid Valve Works?

A solenoid valve is made up of a coil of wire that has a corkscrew shape covered around the piston which is designed out of iron metal. A solenoid valve is an electromechanical controlled device which has a flexible ferromagnetic core in the middle – this core part is known as a plunger. The plunger functions as a small opening.  Upon the magnetic field force; the plunger is pulled in the direction of the coil, and that is how it the orifice opens. This is perhaps the primary working behind the solenoid valve. 

Solenoid Valve Mechanism in Hydraulics and Pneumatics

Usually, the pneumatic valves are activated by the pressure of the compressed air. The valve comes inclusive of cylinder arrangement and piston as well as encompasses some rotating parts known as the actuator. 

Here in the pneumatic valve; the solenoid valve will be controlling the pressure of the air which is flowing towards the actuator hence; it controls the action which is performed by the actuator. The preparation of the hydraulic systems is very much similar to the pneumatic systems. 

In hydraulic systems the fluid is used which is liquid hence; the solenoid valve will be controlling the route of the flow of the hydraulic liquid within the cylinder; which is also responsible for controlling the motion of the ram or piston. 

A Solenoid valve is widely utilized wherever the fluid direction needs to controlled automatically. The valves have been used for a variety of purposes; in the most varied types of electrical devices, equipment, machinery and plants. Furthermore; the solenoid valves are available in a range of varieties which enables to gel accordingly as per the application requirements. Since they are been widely used to trigger the larger valves which are way costly; these solenoid valves are cheaper and economical way to power your systems.
