NPT 2'' Motorized Ball Valve AC24V/DC 12-24V Electrical Ball Valve CR2-02 with Indicator and Manual Override

This is a very well built item, no burrs, nice finish, apparently good quality control. Opens and closes just as described. The manual open/close is accomplished by using provided hex wrench that clips on the back of the unit, a nice touch. As to longevity, that remains to be seen but things are looking good at this point. I installed it on a 2" line coming from a 4500 gallon water tank, just prior to the irrigation pump. I used a 20 second time-on delay relay for the 24 volt irrigation timer signal that activates the 24vac pump power relay and this 24vac valve, so the valve gets the signal first and fully opens just befoe the pump activates. It works great. Then, when it is off, it is OFF, no water comes through this valve and I don't have irrigation seepage through the pump and through downline diaphram valves any longer. It's worth the price, should have done this a long time ago.

The specs say "less than 1-1/2 amps", Not true. When the valve is first commanded to open for the first 0.06 seconds it draws slightly over 10 amps from a 12 volt battery. After that, it draws about 1.25 amps for about 4 seconds, then about 1/2 amp for about 2 seconds and finally to keep the valve open it draws about 0.0075 amps (7.5 milliamps) continuously. That 10 amp inrush surge killed the electronic controls of my water system. After I repaired it I had to design an interface board that could deal with that surge. And yes, I am an electrical engineer. If you are just going to use a battery and switch to control the valve you should be fine, just be aware of the surge and the 7.5 milliamp continuous battery drain could be a problem. Oh, a couple of more things. The "Manual override is a 4mm hex socket on the top of the valve that you have to turn eight revolutions open and close the valve manually. The position indicator is strictly visual, there is no electrical feedback as to the valve position. I would have given the valve five stars if the description had been clear about the inrush surge because the mechanical design of the valve is very good. All stainless steel construction and very well finished machined.

Bought 2. One of them works good. 2nd would not close all the way, requested a replacement. They sent 2 instead of one. I tried just replacing the gear but still wouldn't close so the valve appeared to be the issue. Replaced and working great for 1 week so far. Crossing fingers 🤞 The housing and ball valve appear to be excellent quality. Gear mechanism appears good also. Two good features is the ability to manually open or close in case it fails, and the indicator tells you the position of the valve.

Plastic actuator cover broken on 2 valves that I ordered. Shipping box did not appear to be damaged.
