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.
Power On/Energized:- When the power On input will connect to output1 and output2 will connect to exhaust2 to release holdup pressure in other side.
