QWORK Automatic Gas Tank Valve with US Plug - Suitable for Gas Tanks, Drip Legs, and Compressed Air System Components - AC 110V Power Supply - 1/2" Valve Size Electronic Drain Valve

Works as described, wish it had more of a time delay between purges.

Muy buena recomendada es lo que toda persona que tenga un compresor requiere para mejorar la calidad en su trabajo

This thing is awesome and for the price it is a must-have if you use a lot of air. The first time that it purged I was standing and right in front of it and got covered in water. This thing is great.

This works great to keep the moisture out of my compressor tank Was a little concerned about the short cycle time between blasts. But it working fine and not losing any pressure in the tank. Recommend this unit work good and at a great price.

These drain valves have been working great now for weeks. Made like the one that cost four times as much.

Having had an air compressor tank suffer from rust on the bottom, in a very wet climate, I think this is the perfect solution to keeping water from collecting inside. There are variations of the concept at a variety of price ranges, and time will tell about longevity, but I can't be more pleased so far!

I decided to purchase this after I went to drain my compressor and while trying to open the valve the 90 coming out of the bottom of the compressor busted out. I usually drain it every so often but when you have an auto drain you don't have to worry about it. The only annoying thing is that you can only set it for a short period of time. I really wish it had longer intervals in between.

This works as intended, you can program the interval and time. I interlock it with the compressor pressure switch so it only works when the compressor is charging.

....because of the micro-printed "salad of words" which is supposed to be the manual. Total useless, but the valve works just fine. Pretty good bang for the buck ! 👍

Shorty after installation it failed open and cause the air compressor to run constantly.

Fonctionne parfaitement avec le délai d'attente et de purge !

Last unit I bought from an industrial parts supplier was over $200. One month in, this works exactly as expected. Seems to be solid and well made, no problems so far.

Timer work great and easy to install.
