U.S. Solid NPT Brass Electric Solenoid Valve 12V DC Normally Closed VITON (3/4 inch)

I think the first one I received was a lemon because I couldn't get it to work at all. The replacement arrived and it was installed in minutes and works great! Using this for a grey water tank under my van.

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.

For what it is, it's a five star valve. I have used several of these US solid solenoid valves over the years and have never had any issues. I needed an automatic drain valve for my air compressor and finding the ones online were extremely expensive so I decided to put my own together. I use this valve for that purpose along with a 12-volt DC power supply and a timer. The only thing to note is the operating pressure of this particular valve is 120 psi give or take. I have it on a tank that has a maximum pressure of 175 so it does leak by a bit. So I'm looking for another solenoid valve that will handle 200 PSI.

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.

We use it every day that we're on our boat to turn on/off the propane supply to the stove and we're happy with it. As they warned in the literature, it (the coil) gets hot with continuous use. We cooked Thanksgiving and Christmas dinners with it and it's still working fine. Note: I made the mounting bracket pictured but it does have 2 metric (sorry; I don't remember the size) mounting screw holes in the brass body which helps with mounting options.

Super

This was installed on a low to moderate use lawn mower and in less than a year it developed an issue. When open it gets incredibly hot and then assuming it gets weak while hot it quits delivering adequate fuel to the engine. Bypassing the valve with a hose cured the poorly running engine symptoms. I left the valve powered open for about 15 minutes by itself and it gets too hot to touch with a bare hand.

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.

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。

Awesome product

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

三階のベランダに水栓がなかった為、植木鉢の水やりにこれを屋上の4階の蛇口に取り付け使ってます。ホームセンターで水道用品売り場で継手部品2個を買い。そしてアマゾンで買った12v ワイヤレススイッチ 315mhzリモコン スイッチ を取り付け、三階からワイヤースイッチで操作しています。最後に雨が掛かる所なのでペットボトルで覆いをしました。耐久性はまだ解りませんが普通に使えてます。
