Requirements: the solenoid valve drives the small cylinder 1, sets the timing to open the cylinder for 3 seconds every 5 minutes, and then closes the cylinder. (Circuit diagram and component specifications are preferred) A very simple control can be controlled by a double set time relay. The first time interval is set to 5 minutes, and the second time is set to 3 seconds, so that you can work in cycles. Omron has this time relay. Or you can use two ordinary time relays, one with a power-on delay of 5 minutes and the other with a power-off delay of 3 seconds, and then the two time relays are interlocked. The circuit is more complicated.
