Part I: Original Circuit Building and simulation
Due: End of Unit 3
Consider the pneumatic circuit shown. The following sequence occurs when the push button of
valve M1 is depressed:
a. Cylinder C1 extends
b. Cylinder C2 extends
c. Both cylinders retract
d. The cycle ends. (It executes just once)

Do the following:
a. Fully name all the components of the pneumatic circuit (SP1, SP2, M1, S1, L1, P1, F1,
C1, ...)
SP1-Compressed air supply
SP2-Air service unit
M1-3/2-way valve with pushbutton
S1, S2-Pneumatically proximity switch, solenoid operated
L1-3/2-way roller lever switch
P1-3/2-way valve pneumatically operated
P2-5/2-way valve pneumatically operated
F1, F2, F3-one-way flow valve control valve
D1-Two pressure valve
C1-Single acting cylinder
C2-double acting cylinder
b. Predict, in details, the succession of events when the push button of valve M1 is pushed.
When the push button of valve M1 is pushed. P1 is actuated through D1, since
compressed air is now being supplied to both inputs of D1. When P1 is actuated
compressed is supplied to C1 through F1 causing it to extend. When the piston rod
extends and hits the point 1B2 on the measuring rule, L1 is actuated actuating P2.
Compressed air is forced into C2 though F2 causing it to extend to the right. When C2
extends and its piston rod hits point 2B2 on the measuring rule S2 is actuated initiating
the retraction retract stroke of both C1 and C2 by deactivating P1 and P2 respectively.
C1 retracts when P1 is deactivated through the return spring. C2 retracts when P2 is
deactivated and compressed air is allowed to flow to the back of the piston through F3.
c. In the simulation software assigned by your instructor, open a new file named
Project_Pt1_LastName_FirstName.
d. Build the circuit using the components shown or their equivalents.
