Do you know how Solenoid Valves are used?

Do you want to know how solenoid valves work? Well, this article will explain the basic operations on how solenoid valves are used and how it’s operated. Typically, solenoid valves are used to convert electrical energy into mechanical energy. These valves come in various sizes and shapes. Nevertheless, the shape variation is based on the capacity of these valves, its pressure and various other internal mechanisms.

So coming to the point, how do these valves work?

There are plenty of variations on how valves operate, hence we shall focus on directly operated valves as it’s the simplest version.

The solenoid which is a coil of wire is on top of the directly operated valves. When it passes an electrical current through the coil, it generates an electromagnetic field. This magnetic field basically controls the valve.

There are two types of valves, which is the normally open and normally closed types.

Normally Closed Solenoid Valves
The armature is inside the valve. The solenoid is placed above thus and surrounds the armature completely so that it remains in the middle of its magnetic field. The plunger and spring are inside the cylinder of the armature.

The spring pushes the plunger down in a normally closed type valve making the plunger sit in the down position to close the valve indefinitely. But then again, if the coil accepts an electrical current then it will produce an electromagnetic field and this magnetic field permits through the plunger and will encourage it to move uphill contrary to the spring, consequently opening the valve.

In the middle of the coil, the magnetic field lines are the most compressed and consequently the strongest. This is the reason why the plunger is placed in the center.

Once the electrical current stops, then the magnetic field vanishes and the spring will force the plunger down to close the valve.

Normally Open Solenoid Valve
With normally open valves, the coil sits around the armature but for this, the spring pushes the plunger in the uphill position as a result that the valve is always open except of the solenoid coil is powered.

If a current passes through the coil, it will again create an electromagnetic field but this time the field shoves the plunger instead of pulling it. When the plunger is pushed, it will close the valve and break the flow of fluid in the system.

When the electrical current is motionless, the spring forces the plunger back into the upward position and open the valve again.
