1# What Is the Working Principle Of An Electric Control Valve?

Electric control valve works on the principle of electromagnetic induction. It has a solenoid valve which is an electric coil. In its central position, it has a plunger or ferromagnetic core. When the solenoid valve is at rest position, its plunger closes a small orifice. When it is working, an electric current passes through a coil that creates a magnetic field. This magnetic field creates a force in an upward direction. Hence, it opens the orifice. This opening allows the liquids and gases to pass through it&#;however, the direction of flow of materials and exerted force work in the opposite directions.

2# Which Factors Maintain A Steady Flow Of Materials Through Orifice?

The flow of liquids and gases in an electric control valve depends on these two factors:

1. Orifice Diameter:

The orifice diameter plays a central role in maintaining a flow rate and maximum operating pressure. A small orifice diameter generates more pressure and a more speedy flow of materials through it. Hence, you can easily maintain pressure differences from 0 bars up to the maximum allowable pressure ranges.

2. Magnetic Force:

The amount of electric force generated is directly proportional to the flow of materials through an orifice. Therefore, more magnetic force means a more steady flow of materials. However, a permanent magnet generates a stronger magnetic field than a regular coil.
