Question: will this allow a gravity feed.
Document: Replaced a sticky Blast Cabinet valve. The high pressure can make solenoid valves not work well. This one has been great.
Overall, a fine product.
Loud and hot might work if auditioning for a reality tv show. For a water valve, it is very annoying.Obviously this is magnetic based, and being NC, it will be energized when open. That leaves a loud buzzing/humming noise. The electromagnetic mechanism also heats up quite a bit. I'd be a little worried about using any type of pvc or plastic piping components with this, or for anything flammable.
It is not - it is a plunger type valve with a rubber seal on a spring loaded piston (spring holds it closed when power off, magnet pulls open when energized for an NC valve). That really isn't a problem, but it is may be for some applications. I'm somewhat skeptical of the pressure it could hold against long term, and that the rubber plunger won't wear out with time. The internal path is also restricted.
I'd estimate the throughput to be probably equivalent to a 1/2&#34; pipe diameter. This would not be sufficient for a whole house main line.
I have been looking for 110VAC (24V are easier to get) valves like this for a long time. Finally found it at Vktech. Quick shipping. The packing was not great but adequate - bubble wrapped in plastic envelope - I ordered three for some home projects all working great. Unfortunately at the time of this writing the item is no longer available
Having NC in that case works well, and as the valve only opens when the pump is triggered, the pump is louder than the valve, so it is mostly covered up.If you have a noise sensitive application, I'd look elsewhere, or probably look for a 12/24v system instead, it would probably be quieter.I also want to point out the actuation system on this. It is not what I expected.
Compact, clean design, very well suited for the job planned. But FYI...there is a very audible &#34;snap&#34; as the valve opens or closes (in case a completely quiet operation is needed). Pay attention when you order this as mine came directly from China by USPS and really did take over three weeks to arrive. I can't take umbrage at that because it did declare the long transit time during the ordering process.
Answer: no
