I have an application in which I am basically building one weld

> head which has 2 torches. Both welding torches (TIG) shall have inert gas passing through them.

Both torches, however do not operate simultaneously. They operate alternately.

I want a valve which would switch the inert gas between those 2 torches alternately; but turn off the supply completely when not in use.

I am looking for a direct solenoid valve. What kind of valve would you suggest for such an application?

> Would that be a 3 way or a 4 way valve?

> Pressure requirement is say 120 psi max.

Please help!!!

Don't hold your breath waiting for an answer from this forum. Most who frequent this one are the same ones that have already answered at the other posting.

In fact I beleive there are a lot more posters there than here.

Fluid Power is an orphan discipline that has a few diehards but few trained persons working in it. When I say trained I leave out the "College of hard Knocks."
