How Solenoid Valves Work

Learn how Solenoid Valves Work and where they're used in the Mechanical Trades. Learn the difference between a Normally Open and Normally Closed Solenoid Valve.
See examples of how they're used in a Water-Cooled Heat Pump System to meet the ASHRAE 90.1 Standard. See how they're used in a Refrigeration Circuit.

[@DimuthuJanakaAbeysinghe]

Thank you very much for your explanation... 🎉🎉🎉

[@MEPAcademy]

Thanks for watching.

[@siranjeevi4125]

Does it prevent from which cause while pumpdown?

[@MEPAcademy]

? The solenoid can be used as part of the pump down cycle.

[@alvinjayreyes7478]

what if , if the armature tube is not closing ,even the coil is new?

[@MEPAcademy]

I'm not sure we understand the question. Can you rephrase your question.

[@alisinoir3348]

at what position, is the solenoid valve is supposed to be fixed

[@MEPAcademy]

Depending on the application, the solenoid valve could be either normally open or normally closed.
