How Solenoid Valve works?

We will learn how solenoid valve works. we will learn 2 way solenoid, 3 way solenoid, 4 way and 5 way solenoid working. we will also learn operation of solenoid valve.

How 2 Way solenoid valve works?
or
How 2/2 solenoid valve works?

2/2 Solenoid valve also known as 2 way solenoid valve or 2 way SOV or 2/2 SOV.

1:- Two way or 2/2 SOV have 2 ports.

2:- Two way solenoid used only for on/off control action like draining, sample handling.

3:- One port for inlet and one port for outlet.

4:- Hook up inlet/outlet port from process.

Power Off:- When solenoid valve is DE-energized input will not throw to output.

Power On:- When solenoid valve is energized input will throw to output.

How 3 Way solenoid valve works?
or
How 3/2 solenoid valve works?

3/2 Solenoid valve also known as 3 way solenoid valve or 3 way SOV or 3/2 SOV.

1:- 3/2 solenoid valve have 3 ports. One Input,One output and One Exhaust.

2:- This type SOV use to operate single acting actuator.

3:- One port for Input,One port for output and One port for Exhaust.

4:- Hook up inlet/outlet port from process.

Power off/ De-energized:- When the power off input will not connect to output but output will connect to exhaust to release holdup pressure.

Power ON/Energized:- When the power on input will connect to output.

How 4 Way solenoid valve work?
or
How 4/2 solenoid valve work?

4/2 solenoid valve also known as 4 way solenoid valve or 4 way SOV or 4/2 SOV.

1:- It consist 4 port.

2:- One input , 2 nos. Output and one Exhaust.

3:- This type SOV use to operate double acting actuator.

4:- Hook up Inlet port to Input and both output to double acting final element.

Power off/ De-energized:- When the power off input will connect to output2 and output1 will connect to exhaust to release holdup pressure in other side.

Power On/Energized:- When the power On input will connect to output1 and output2 will connect to exhaust to release holdup pressure in other side.

How 5/2 Solenoid valve work?

5/2 solenoid valve and 4/2 solenid valve working are same.

1:- It consist 5 port.

2:- One input , 2 nos. Output and 2 Nos. Exhaust.

3:- This type SOV use to operate double acting actuator.

4:- Hook up Inlet port to Input and both output to double acting final element.

Power off/ De-energized:- When the power off input will connect to output2 and output1 will connect to exhaust1 to release holdup pressure in other side.
