## 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.

### ⭐⭐⭐⭐⭐ 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.
