Simply put, a solenoid valve is a valve that’s operated electronically, so they’re very handy for controlling the flow of air or fluid via a remote electrical switch. That’s why they’re so common in pneumatic systems and ordinary plumbing—you’ll find solenoid valves in a lot of applications, from air horns and pneumatic shifters, all the way to home HVAC humidifiers.
And while they’re relatively simple devices, it can be easy to install a solenoid valve incorrectly, hence why we liked this video from the folks at Kleinn Air Horns.
Not only will this video walk through a typical solenoid valve installation, it’ll explain in basic terms what a solenoid valve does and how it works. It’s a good watch for folks without a lot of electrical experience, and really anyone working around pneumatic or hydraulic systems.
