U.S. Solid 1/2" Stainless Steel Electric Solenoid Valve 12V DC Normally Closed

This is a very good product. I tried to use this for an RODI setup for continuous use and it gets very hot. The manufacturer says that it is not designed for continuous use and gets very hot, my fault for not reading. But I did end up testing it on some other stuff anyway and it works great. Also the company makes a motorized ball valve made for continuous use, since the solenoid was very good for what it was designed to do I’m sure that the motorized ball valve will be just as high quality. A+

Works perfectly! Initially I installed a 12v fuel pump, thinking it had a built-in shut off valve, it didn’t. So, I installed this shutoff valve in-between the aux tank and the 12v fuel pump. I wired both to the same switch, both- open and pump at the same time. Works perfectly.

I am using this 1/2" valve for my diesel xfer tank in my Ram 3500. Works great along side a little 12v pump to refill the smaller truck tank faster than relying on gravity feed alone. It does get pretty warm to the touch. So far no good. I will update this review if necessary.

I bought 2 other brands and they both leaked. This one is working great!

A little larger than the one that I am replacing, but very functional.

I originally posted the negative review below, and almost immediately after posting it, the owner of the company not only issued me a credit, but he sent me an email acknowledging they had a manufacturing problem. He also offered to send me out an immediate replacement, and asked that I call him personally. So, I called, and he answered - on a Sunday. As background, I bought this solenoid over a year ago, but had not installed it until last weekend, so I had exceeded the warranty period and they were under no requirement to address my concerns. I was very impressed that he admitted they had a manufacturing/supplier problem and they were replacing the units. He explained that some people do not understand these types of valves are not intended to be energized (i.e. be kept in the on/open position) for an extended period of time. The valve is opened via an electromagnet which by their very nature will generate some heat over time. That is both entirely reasonable and in line with the additional research I had done. This was also in line with my particular need (to open a low-pressure LPG line in a boat/RV when cooking, and automatically shut off the supply when the switch is turned off). I also determined this is consistent with other solenoids. He went on to explain that there are better solutions for valves that need to be kept open for extended periods. I put in the replacement, and am happy to report that while the solenoid gets warm, it is much cooler than the first one, and the draw went from 2 amps on the first unit to about 1.2 amps on the replacement. As sailors, we are always concerned about battery draw as we sail for many hours without running the engine, so unnecessarily drawing down our battery bank is not something we want to do unnecessarily. In short, I am extremely impressed by someone who cares enough about their business to fix a problem even after the warranty period expires - and to be honest when a manufacturing or supply problem is discovered. I will now go out of my way to buy from US Solid in the future. ORIGINAL REVIEW: I bought this valve as I had to repair the system on my boat about a year ago. I finally got around to replacing my old solenoid which was quite rusty, but still worked. Upon hooking this up, it ran WAY hot, measuring over 180 degrees on the outside. Now I have to replace it immediately after putting it on. I see they no longer sell this unit.

I used this for my auxiliary diesel tank in my pickup. Worked good for the first week, then it leaks and never shuts off. It leaks 1/4 tank of fuel overnight (about 8 gallons)...almost overfilled my main tank! So I took it off to inspect it for something stuck in the valve & found nothing...it is just leaking through the valve, not seating/sealing. After my long trip, it's past the return date, so this thing is useless, this valve is a waste of money & time....NEVER AGAIN!!!!

I ended up returning this as it wasn’t actually what I needed to solve my problem, but nevertheless, it seemed to be a good quality product and I would purchase again if needed.

オイルリフターで先止め方式で制御してます。古い電源アダプターで市販のタイマーを噛ませて使ってます。安くて十分。

I used this valve in my LG Top load washing machine. Because the original valve in washing machine is very small and filling took much time. Total washing time is about 2.5 hours. After fitting this solenoid valve, water fills in two minutes and the washing is completed just in 45 minutes. Zero leakage. Best quality. Sturdy.

Work good for my app
