U.S. Solid 3/4" Brass Electric Solenoid Valve 110V AC Normally Closed Non-potable Water, air, Diesel

I purchased this solenoid valve and have been using it now for a little over three weeks in a water pipe application with a thermostatic controller. The quality of the valve is excellent and its functionality is reliable. Mine operates once "on" and once "off" for a total of 6-9 hours "on" time, 7 days a week during the summer (May thru Sept). The solenoid valve is easily disassembled and each of the three main components appear to be easily replaced. Mine did not come with any instructions, but it seemed pretty straightforward as there are only two electrical wires. Some have complained about non-standard pipe threads, but it is definitely NPT. I had no problems connecting red brass, galvanized, black iron, or PVC to the 3/4" female threads. One very important thing to remember is that the valve is unidirectional, not bidirectional, and is stamped with a small flow direction arrow on the brass body. If you happen to install it backwards, the valve becomes normally-open instead of normally-closed and gives the impression that it is a "normally-open" valve. I don't think it is intended to operate long-term in this manner, but I know mine reacted that way before I saw the small flow arrow stamped into the side of the brass body. The valve does get pretty warm when actuated, but not extremely hot. Reports are that the valve is not designed to stay actuated for more than 8 hours at a time, and the solenoid may burn out if regularly operated for longer periods of time (this is because the solenoid coil has to remain energized to hold the valve open). Overall, I recommend this product. UPDATE: After 6 weeks of operation on a daily basis, the solenoid valve is still operating well. Cold, well-water running thru the valve. Solenoid is hot while in "open" mode, but not burning hot, and you can still grab it and hold it for a while without burning your hand. If hot water were running thru it, I don't think I could expect a long operating life before burning out the solenoid, because of the specific way/application I am using it.

I installed this valve inline on my 1” natural gas line, between the meter and interior distribution manifold, along with both a shutoff valve and a bypass valve (for use when needed). It operates flawlessly during routine testing. During normal operation there is no reduction in gas pressure or impact on appliance performance. The valve is hardwired for automatic closure when triggered by my natural gas sensors. All fittings sealed perfectly with no leaks on the first attempt / installation. FIVE STARS

I purchased this solenoid valve to use in a 1" water supply line that 'demand feeds' a water storage tank when a float switch in the tank indicates the water level in the tank is getting low. The solenoid valve has been working flawlessly for several months. I installed the valve about 3' away from a pressurized water bladder tank, thinking the tank would absorb most of the water hammer induced by this valve snapping closed, but it didn't. There was severe hammer in the line, due the very fast shut-off time this valve delivers. I mitigated this issue easily with an inexpensive (large) water hammer arrestor, placed near the inlet side of the solenoid. Now I can barely hear the valve snapping shut, and there's no hammer whatsoever in the pipe. This solenoid is a solid piece of work, to be sure. I removed the threaded plastic wire entrance cover to the solenoid, and replaced it with a metallic metal flex conduit fitting, and soldered the pigtail wire leads to standard ROMEX wire, shrink wrapping them neatly inside the conduit. A single nut loosens on the top of the solenoid, allowing the solenoid housing to be rotated to ANY position (full 360 degrees of freedom) to 'point' the conduit in an optimal direction. The valve body is clearly marked with inlet and outlet direction. Very satisfied customer.

I have a water tank on the roof of my building. I installed this little guy on the pipe, and fit a gallon plastic jug around it to protect it from the elements. I ran a wire downstairs, installed it with a timer switch, and was done. It works perfectly. I honestly couldn't ask for anything more. Since I only activate it for a minute or so, I imagine it will pretty much last forever. Edit: Worked absolutely perfectly for two days - then quit working. I'm on the fence if I'm going to buy another one.

this solenoid is used for controling the air coming off my air compressor and i use a mark time timer to control the solenoid i gave this 3 stars due to the threads on the solenoid was not cut deep enough so a leak resulted the mpt connector bottomed out before tightening completely had to cut the pipe (copper) sawed off 3 threads on the connector and was then able to tighten without leaking other than that it works well it is difficult to find a solenoid that will handle 175 psi plus and by using the mark time timer i do not have to remember to shut it off. hot dang susie bob

Excelente y muy buen precio.

seems to be super high-quality valve. so far I like it and it’s been working great for a couple of months does make it loud bang when it shifts to open, as others have mentioned on here, but not a big deal for me I would definitely buy again. I know it’s gonna last for many years.

Didn't last 4 months before seal in solenoid started leaking. Apparently there is no warranty. As far as I can see this product is not worth installing.

ル部の操作がいらないは

Buena calidad y material, funciona muy bien

Works great for my application straight forward hookup. Make sure flow is in the right direction.

まだ正式に設置していませんが、水の出止に正常に働いています。

Installed 1.5 year ago in store RO water system and still working good so ordered second one too replace the flush valve.
