Im a Journeyman Plumber and aside from traditional Plumbing systems i have also built Mechanical rooms. Ive seen Solenoid Valves and installed them along our systems but never really knew how they work. Next time i see a systems operator i will tell him to thank me for installing them so he doesnt have to walk the system and can enjoy his comfy chair

I very rarely see engineers in the plant. Theyre usually in their office doing fancy math that only they would use, and dream up ideas that wont work in the real world as they dont possess field experience. Lastly they usually ignore ideas that Operations suggest since they didnt come up with it themselves.

So in this video there are two versions - a normally open and a normally closed. Is there a toggle version so it only needs power briefly to switch rather than constant power to maintain one of the two states?

Ive run current in the opposite direction and the solenoid acts exactly the same, i. e. it did not get pulled in the other direction as one might expect. sooo yeah are you just simplifying the explanation?

Great video. I worked with hundreds of these in the hospital I worked in. Boilers, dishwashers, laundry etc all have lots of them. They can make a loud click when they open.

Simple and work great. When they get old, intermittent, partial, no operation and leaks happen. Automotive systems and residential sprinkler systems are classic examples.
reply

Is it possible to vary the strength of the current to control the amount the valve is open, or is a stepper motor valve better suited for something like that?

This is why maintenance techs are in such high demand lol
Im pretty sure they meant the real hands on engineers.

Fun Fact: In 1910, ASCO Numatics became the first company to develop and manufacture the solenoid valve
