QWORK Automatic Timed Condensate Drain Valve, 1/2" AC 110V 2-way Direct-acting Drain Valve US Plug

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

Great price, great delivery time, everything went off without a hitch. The price was less than 1/2 of what the vendor that I bought my air compressor from was.

Great price. Keeps the water out of my shop air system

Wish it would go much longer between cycles but it works fine, one of the included 90′ valves was worthless so I removed a *. It doesn't actually fit the included parts and leaked air, used one I already had. Aside from that valve it works fine. It cycles more often than I need it to, 1 time a day would be fine for me so I just unplug it unless I'm in the shop, my air is shut off if I'm not there anyway.

WORKS GOOD

Reducing to 1 star. DO NOT buy.Wanting to install my tank drain with proper fittings, I spent about $50 at the hardware store to pipe in solid brass lines. On the outlet side of the solenoid, I ran 3/8" copper tubing to route the condensate outside of my shop. After finishing the install I pressurized my tank, cycled the solenoid with the test button a few times, impressed myself with how quiet the drained air is (if an auto drain hasn't jump scared you, you haven't spent much time in a shop) and called it good. About three hours later, I walked back to my compressor room and was shocked to discover the solenoid was stuck open. I checked the hour meter on the compressor, and it had clocked 2 hours of run time since the auto drain install. The install that I had completed 3 hours earlier. Given the 45-minute drain time I set, that means that the FIRST TIME it was supposed to drain for 2 seconds, it failed, causing my compressor to run for 2 hours. The tank was almost too hot to touch.I have uninstalled this auto drain, purchased a DeWalt auto drain, and another quart of compressor oil to change out the baked oil. In trying to save a few bucks, I ended up spending over $200 to rectify the failure of this POS tank drain.Original review:I should have watched the installation video in the reviews first.The taper pipe thread of the solenoid block is not designed to be used with the straight pipe thread of the filter/shutoff. Guy in the video epoxied the threads together, which IS an option. The threads aren't going to come apart, it's not a safety concern, but it's extra effort I shouldn't have to do.It's a cheap kit, and it shows.Also, and this is me being nit-picky, while the solenoid is 110v rated, it's 50Hz. Only speaking for the US grid, power is supplied at 60Hz. Again, it'll work, but it could be better.You get what you pay for.

As advertised, longest interval is 45 mins. Threads are leaky - even with Loctite PST. Ended up having to machine some off male portion to gain more taper engagement and ultimately soldered the joint and now it works well. I wired mine into the compressor and installation is pretty clean. Happy. Warning, this thing will startle you every 45 minutes or so...even when you're expecting it! I feel like I am preserving my $850 Quincy's tank, though - so worth the trouble. She'll pump once every 20 hours or so, keeping lubrication in place - and I have air on tap all the time!

Using these in a Heat treating plant that has lots of water in the air lines due to the temp diffrence. Hve it set to drain for 5 seconds ever 1/2 hour and has worked well for our needs.
