Review on 💧 Efficient Water Flow Control with HFS Electric Solenoid Valve by Chris Russell

(12V 3/4 NPT version) which I used for my cold water line at home (so 60psi). It works as intended and has a fairly simple design overall. The rubber membrane is attached to a metal rod that is pulled in and out by an electromagnetic field. The rubber (which looks like Buna or EPDM) will most likely be a weak point that will fail after a few years and cannot be replaced as it will be pressed against the metal part of the drive. Problems: The thing gets hot. Very hot. I measured 170F after some time. So hot the whole room smells of gas leaking from the solenoid wiring. Such solenoids get hot because that is part of the behavior of electromagnets. However, I'd wager that this will cause the voltage regulator to fail prematurely, which is probably built in due to the lack of a proper heatsink outside of the sleek metal case. I *strongly* recommend that you install a fan to blow air in if you plan on running it for an extended period of time. I'm constantly updating all my reviews, so if there's no "EDIT" here, then we'll assume it's still working fine for me. EDIT: It looks like these things use mild steel springs, so they rust and want to bind. Don't leave this thing on 24/7 or you won't be able to turn it off.
