Question

e adjustable one-way flow control valve 1V2 in the control circuit shown below the supply port port are accidentally interchanged. Which would be the effect of this mistake on the operation of the The piston rod of cylinder 1A will retract unthrottled at all times Both chambers of cylinder 1A will be pressurized and its piston rod will remain in mid-position After retracting cylinder 1A, it can not be brought in the extended end position anymore. The piston rod of cylinder 1A will be permanently in the forward end position. control circuit? The piston rod's retracting movement will be throttled 2V1l4

Explanation / Answer

Correct Answer-

E. The Piston valve retracts movement will be throttled.

Description-

1. There are two Pneumatic circuits with solenoid actuation, but there is no electrical connectivity given, thus both circuit will work independently.

2. Now circuit with 1A Cylinder diagram throttle valve with reverse flow check valve ( 1V2) is placed such a that retract movement of the cylinder (1A) will be throttled, Thus check valve will remain closed while cylinder retracts and no throttling when cylinder (1A) extend.

3. So, even after interchanging or without interchanging the position of port i.e. supply and working port the piston retract movement will be throttled.
