Beduan Brass Electric Solenoid Valve, 1/2" 220V Air Valve Normally Colsed for Water Air Gas Fuel Oil

Vork perfect in my vatersupply pipelines. Easy to install and seems to be of good quality.

I'm giving this 3 stars. I got a new 80 gallon air 220 volt compressor that feeds the air lines in my workshop, which has some minor leaks. Turning the line valve off at the compressor allows it to maintain pressure for days or weeks, but leaving it open causes the tank to lose most of its pressure by morning. I got tired of manually turning the valve or forgetting to. Therefore, I got this 220v solenoid to automate that. Turn the compressor on and the solenoid activates and the air lines pressurize. Turn it off and the compressor retains pressure. Here's my issues: 1 - The solenoid buzzes and gets hot. I get it, solenoids do that. But, I feel it could have been significantly reduced. 2 - The wiring connector fits a 1/2" knockout hole. That connector broke off. 3 - It leaks on the input side. Seems like this would be my issue, but I have attempted to fix it a couple times. The output side doesn't leak. I don't have any other leaks near the solenoid. This isn't rocket science. This completely defeats the purpose of the solenoid.

I bought the first one in late April 2023 for a machine that had a valve in need of replacement sometime in the future. For various reasons, I didn't get to install it until late Jan. 2024. Installed it, turned it on for about 10 seconds and it worked fine. Turned it off for about 20 seconds and then turned it back on, and it didn't work. Tested the continuity of the coil and had none - the coil was toast. I wrote it off to 'Ya know, it happens. Sometimes a bad part comes off the line.' (I've done industrial maintenance and service work for over 35 years in manufacturing, I get it) I ordered another valve and put it on the day it arrived (today), didn't work at all. Continuity check of the coil showed it was toast right out of the box. Both valves were ordered and shipped as 220V AC coil valves, and before putting each on, I tested the voltage on the coil wiring. This ain't my first time hooking up something as simple as a solenoid valve, as a matter of fact, it doesn't even fall into the first several thousand times I've done it. But it IS my first time getting two brand new components (even Chinese made crap) that were bad right out of the box. I just dropped a little over $120 bucks on a non-Chinese 1/2" solenoid valve (hard to find), and I'll be returning this paperweight that has cost me immeasurable amounts of time, money, and pissed offedness. I hold my nose whenever I buy Chinese crap, but I used to think it was because they were trying the best they could in spite of their skewed economic incentives in the system, now I'm becoming increasingly convinced that they are doing this on purpose.

Value for money

Easy to work & install

Super Poor quality! Bought 4 solenoid valves and none of them worked...

Good
