## Questions & Answers

**Q: Can this valve be mounted vertically**
A: Hello, the solenoid can be mounted in any position,.

**Q: Can it be used to connect a rotary vane vacuum pump to a tank with atmospheric pressure ? Will the air leak through the closed valve?**
A: As long as you observe the correct orientation of the valve (in/out direction), it doesn't matter, a vacuum on the low side (out) with atmospheric pressure on the high (in) side is no different than putting about 15 psi on the high side and atmospheric on the low - to a valve, it's all the same.

**Q: How much does the valve move?**
A: don't understand the question. the moving parts are internal.  it opens to provide what ever it takes the line to fill  How far that is I don't know. If it is a half inch line the valve will move a half in.

**Q: In closed position will the valve allow flow in the reverse direction if there is reverse pressure up to 0.14 Mpa?**
A: No, this is a one-way normally closed solenoid valve, it does't allow reverse flow.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great - BUT be aware that there are a few caveats...
*by B***A on February 10, 2020*

This is verifiably a direct acting solenoid valve, meaning that all movement of the diaphragm is from the energized coil itself. It does NOT require a minimum operating pressure to fully open, which is a much more common design to find. However, that capability comes at a price: operation requires a very powerful coil. But powerful coils draw high CURRENTS and cannot sustain that full current for more than very short periods without OVERHEATING. If your application only requires that the valve be energized for 5 seconds every few minutes and NO MORE, you'll probably be fine using it as-is. Otherwise this MUST be driven using some form of active current/voltage control, i.e. PWM.The resistance of the coil for the 1/2" 12 VDC version measures 5.5 ohms, drawing just over two amps at 12 volts, dissipating 26 watts of heat, which is quite a lot in such a small space. The secret to success is understanding that full power is only needed for a brief time to initially open the valve but a MUCH smaller current will HOLD the valve open. In my case I've got an Arduino Mega driving an H-bridge motor controller that actually powers the coil. To open, full current is supplied for about 100 milliseconds after which it drops to a fraction of that by switching to PWM with around a 30% duty cycle to maintainin the open position. Using this scheme I've yet to have a failure to open or to stay open and the body of the valve never goes above ambient even after hours of being powered.The only other things to be aware of are that it makes a VERY loud click when activated and the threads are NOT NPT, they are not tapered - so expect to use a LOT of sealing tape if using conventional pipe fittings.

### ⭐⭐⭐⭐⭐ Great for rainwater sprinkler system
*by I***N on July 23, 2024*

These are great little valves. I use them for my rainwater irrigation system where I don't have enough head pressure to keep a standard sprinkler valve closed without the pump running. They're rated for 12VDC, but work great with the 24VAC I had with this sprinkler system - I'll report back if they fail because of this, but so far, they seem to be working great!

### ⭐ Bought this twice in 9 months and both were bad right out of the box.
*by J***R on February 3, 2024*

I bought the first one in late April 2023 for a machine that had a valve in need of replacement sometime in the future. For various reasons, I didn't get to install it until late Jan. 2024. Installed it, turned it on for about 10 seconds and it worked fine. Turned it off for about 20 seconds and then turned it back on, and it didn't work. Tested the continuity of the coil and had none - the coil was toast.I wrote it off to 'Ya know, it happens. Sometimes a bad part comes off the line.'(I've done industrial maintenance and service work for over 35 years in manufacturing, I get it)I ordered another valve and put it on the day it arrived (today), didn't work at all. Continuity check of the coil showed it was toast right out of the box.Both valves were ordered and shipped as 220V AC coil valves, and before putting each on, I tested the voltage on the coil wiring. This ain't my first time hooking up something as simple as a solenoid valve, as a matter of fact, it doesn't even fall into the first several thousand times I've done it. But it IS my first time getting two brand new components (even Chinese made crap) that were bad right out of the box.I just dropped a little over $120 bucks on a non-Chinese 1/2" solenoid valve (hard to find), and I'll be returning this paperweight that has cost me immeasurable amounts of time, money, and pissed offedness.I hold my nose whenever I buy Chinese crap, but I used to think it was because they were trying the best they could in spite of their skewed economic incentives in the system, now I'm becoming increasingly convinced that they are doing this on purpose.
