## Description

desertcart.com: HFS(R) Electric Solenoid Valve Copper Normally Closed for Water Air Gas (12V DC 1IN NPT) : Industrial & Scientific

Review: Reliable! - Been using for an air ride setup dump valve. Has held up to the elements for a few years and has good flow as well as reliability.
Review: Workd great for a t-shirt air cannon! - I bought this for the high school robotics team to be the heart valve of a t-shirt air cannon for use at football games and Mardi Gras parades. With about 60 psi and 80 milliseconds valve open time and properly rolled shirts, we could put them in the upper rows of the stadium. We never did try to figure out the switching time, but it's a very few milliseconds, both open and close, which helped us get more launches from a tank of pressurized air. Note - not for continuous use in the open position - if you want that, get a motorized one which switches more slowly but doesn't use power to hold position.

## Features

- [MATERIAL]: The product is mainly made of cast copper with copper coil, which improves the strength and applicability of the valve
- [SIZE]: 117mm*86mm (4.606 '' * 3.386 ''), thread diameter: 32mm (1.26 ''), interface pipe diameter: 1 '' NPT thread, flow diameter: 25mm (0.984 '')
- [N/C]: The solenoid valve is normally closed, which means it is closed when the power is not supplied, which effectively ensures the safety of use.
- [WIDE APPLICATION]: Applicable temperature: - 5 ℃ ~ 80 ℃,Working pressure: water, air: 0 ~ 7kgf/cm2. Working environment: water, air, compressed air and some stable gases.
- [MATTERS NEEDING ATTENTION]: Amps power required by adaptor: at least 2A. As the product is normally closed solenoid valve, the working time shall not be too long, and the working time is recommended to be less than half an hour. If more than half an hour will begin to appear heating state, after the solenoid valve heating, try to let it rest for half an hour before working.

## Questions & Answers

**Q: What amperage are these at 12v DC?**
A: i use 110vAC... works great-... just tried 1 amp 12vDC... does not work... only works with 110vAC... as it says on device... ((( the 12v ones are like $2.40 each... way cheaper than the 110vAC.... ))) trust me bought both... for electronic engineering project... try ((12V-DC-1-2-034-N-C-Electric-Solenoid-Valve-Magnetic-Water-Air-Normally-Closed )) works great at 12vDC@1 amp or google this part number... ((112048094074)) since i bought it off ebay... amazon may have it but i know that part number (( 112048094074 )) works excellent if you wish to use 12VDC instead of 110vACif you need any additional help... message me on FB  www.facebook.com/hackertalkz

**Q: Which wires are positive and negative on the 12v model**
A: The wires are reversible on this one. Works either way. Just verified on the one I own

**Q: "George R.…" understood needs 12v, but how I connect to my 12v pump, without burning out the pump?**
A: Do some research on how off the grid pressure pump systems work. I don't think this valve is what you're looking for.

**Q: Will the valve open with no pressure? Trying to use these in line with a peristaltic pump...**
A: the valve does not care about pressure it opens and closes by the solenoid when elec is applied.

### ⭐⭐⭐⭐⭐ This one works
*by S***A on March 26, 2024*

Bought this to replace an air horn solenoid that stopped working. I'm also going to replace my regulator, it seems to drift 40 psi from how I set it. I'm like it at 60 psi, it drifts down to 40 psi and my horn sounds horrible. When it drifts up to 80 the solenoid won't open. This solenoid opens at much higher psi so a wondering regulator isn't a problem. Eventually I'll get around to replacing the regulator but until then this is a great solenoid. Just don't use it if the temperature is below 23*. The valve will stick open and your air horn will blow until the tank is drained.
