What Is A Solenoid Valve?

This is why maintenance techs are in such high demand lol

I’m pretty sure they meant the real hands on engineers 😂.

Very good

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 ?

👍

Very good

👍👍

Yes the Vacuum pumps in the sterilization systems I repair uses those to control water inlet.

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?

Could you please make a video on district heating system:)

I sent a comment today on a solenoid video of 3 years ago and I don't think anyone will see it so here it is again:
I am building a device that will make super-heated steam in a small 1" by 25cm pipe. The pipe will be heated to 400°C. I want to inject an Arduino controlled amount of water into the pipe on one end which will immediately vaporize and become super-heated steam exiting via a 1/4" pipe on the other end. I was planning to use a fuel injector, but I think the temperature is too hot. My current thinking is to use a 12v DC solenoid valve and a stainless-steel needle. Any advice and suggestions?
Thanks in advance,
Mike

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. They’re usually in their office doing fancy math that only they would use, and dream up ideas that won’t work in the real world as they don’t possess field experience. Lastly they usually ignore ideas that Operations suggest since they didn’t come up with it themselves.

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

What if it burns?

Thank you for sharing 🙏👍.

solenoids! the best way to safely test shooting a firearm in a stupid way!

Lol engineers don’t run around opening and closing valves, operators do.😂

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

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.

Thank you
Well explained.

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?

One video for solar panels 🙏
