1.0 INTRODUCTION
Pneumatic circuits can be controlled by electric circuits. Electro-pneumatic control

consists of electrical control systems operating pneumatic power systems. In this
solenoid valves are used as interface between the electrical and pneumatic systems.
Devices like limit switches and proximity sensors are used as feedback elements.

In Electro Pneumatics, the signal medium is the electrical signal either AC or DC
source is used. Working medium is compressed air. Operating voltages from around
12 V to 220 Volts are often used. The final control valve is activated by solenoid
actuation.

Inside the solenoid valve, there is a coil of wire through which an electric current
is passed. It produces a magnetic field which attracts an iron armature. The movement
of the armature operates the valves. When the electric current is not following, a spring
pushes the iron armature out of the coil. In opposition, the iron armature is attracted
into the coil by the magnetic field when the current flow.

2.0 OBJECTIVE
Upon completion of this practical task, we should be able to:
1. To draw and construct an electropneumatic circuit diagram using double-acting

cylinder.

6.0 CONCLUSION

In this practical task, we have learned how pneumatic circuit function. Starting
form pressing the push button until the cylinder moves. The cylinder will extent
after 3/2-way push button is pressed, the compressed air will flow through 5/2-way
DCV. Then, the compressed air will flow into one way control valve to control the
air flow and pushed the cylinder. The cylinder will retract if the other push button
is pressed.

In conclusion, we able to draw and construct an electropneumatic circuit
diagram using double-acting cylinder.
