Solenoid Valves
How does a solenoid valve work?
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, saving time and money. But how does a solenoid valve work? Solenoid valve working
principal. 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.
