Review on 12V Brass Solenoid Valve, 3/4" Electric Air Valve For Water, Air, Gas, Fuel And Oil - Normally Closed By Beduan by Donald Cummings

I bought this to turn on water for my outdoor sprinkler system. My goal was to attach it directly to the master port 24V outlet on my sprinkler controller so that I would turn on water only when watering. To make a long story short, it didnt work because the sprinkler controller could only handle 750 mA and this valve, by itself, requires 850 mA (950 mA during initial activation). I could of course use a relay, and I was prepared to do that, but then I discovered this thing also heats up way beyond a level I consider safe. It is operating at 20W and the water does not cool it enough when the drip lines are running. So I gave up and ordered a different valve (https://www.amazon.com/gp/product/B06XX6XYD8/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1) which uses a motor instead of a solenoid and pulls a fraction of the current and stays cool.This valve does work, however. If you can handle the heat and the current, it will work for you. But to put this in perspective, this valve pulls far too much current when compared to other solenoid valves. Most 24 V AC/DC solenoids pull about 600 mA during turn on and then quickly drop to 300 mA when the valve is open. That was what I was expecting.
