I'm in the process of upgrading garden sprinkler control to use some automation and looking for recommendations about "good" solenoid valves and reasoning to select among the options of 12 VDC, 24 VDC, 24 VAC, 220 VAC. Now, the system works with manual Sanwa ball valves and blue 1/2" PVC pipe. No need to change all the sprinklers and pipe. Just replace the 4 valves with something smarter.
I have in mind a 4-zone solenoid valve controller with manual set timers (located in the control box). I don't want a Wifi control unit. The best looking control box I have found online is this: https://ttscontrol.com/product/ตู้คอนโทรลตู้ควบคุมโซล-2/ . They offer options for compatibility with 12 VDC, 24 VDC, 24 VAC, 220 VAC solenoid valves. I appreciate any recommendations on "good" solenoid valves and reasoning for selection of a particular electrical configuration for the valve control. Thanks in advance!
