Solenoid valve

How does a solenoid valve work?

Solenoid valves are one of the most commonly used control valves in fluidics. They come in a range of designs, but each solenoid valve has the two same basic components that make it what it is. Have you ever wondered how a solenoid valve works? Read on to find out more about the working principle of the solenoid valve and discover our fantastic range of Maxseal solenoid operated valves.

What is a solenoid valve

Solenoid valves are electromechanically operated valves that convert electric energy into mechanical energy. Their main purpose is to regulate the movement of gas or liquid and eradicate the need for an engineer to manually control the valve, which will save the application both time and money.

Solenoid valves are used in fluid power systems, to control cylinders, fluid power motors or larger industrial valves and can be used for a wide array of industrial applications, including general on-off control, calibration and test stands, pilot plant control loops, process control systems, and various original equipment manufacturer applications.

As solenoid valves are used in the fluidic industry, their material must be compatible with fluid. Solenoid valves are therefore most commonly made out of brass, stainless steel, aluminum, and plastic.

How does a solenoid valve work?

Solenoid valves consist of two basic parts: a solenoid (or electromagnet) and the valve. The valve body is made up of two or more orifices/openings, whereas, the solenoid is home to several important parts, including a coil, sleeve assembly and plunger.

Solenoid valves work by employing the electromagnetic coil to either open or close the valve orifice. When the coil within the solenoid is energised, the plunger is lifted or lowered to open or close the orifice. This is what in turn controls flow, regulating the movement of gas or liquid.

Advantages & disadvantages of a solenoid valve

One of the main advantages of solenoid valves is their versatility. They can be used in an array of industries, for a wide variety of applications and are perfect for a broad range of liquids or gaseous media. They are also an extremely efficient way of controlling flow, as they require very little wiring, expense and effort compared to other valves.

A solenoid valve’s biggest flaw is its capability to handle dirty or contaminated fluids or gas. Foreign contaminants can collect in the solenoid valve’s parts and impede operation. It is also very important that the correct voltage is applied to these valves.
