How does an AC solenoid valve works???

[Helder Silva]

Hello!!!

I know how a DC solenoid valve works. Applying the same principles to an AC type the electro valve would be always opening and closing, since the electrical current reverses each half cycle.
à How can an AC solenoid valve be kept always open or closed dependent on its operation?
à What is the architecture of an AC solenoid valve (I never opened one)?

Best regards and an happy 2009

I'm trying to figure this out as well. This was an interesting article that I found on the subject:

Hope that it helps.

hello,

im khairul from malaysia..
im a new comer in valve engineering.so,i need some help to describe some good information to me.
Actually, i have a job offer from one companies in malaysia,this companies plan to growth the bisness in valve area.So, im one the team to handle about it...I need a help to know.how can i start to measured it.

I'm thinking it has a diode in it that can support the load of how much current is passing through and can prevent it when it travels the opposite direction. so if thats true it will also support dc one way.

Did anyone find how an ac solenoid valve works? I just wondering that why the valve always open or close when we apply ac signal. Cause sign of ac signals always change each period. and magnetic field always change too...
