distribution valve

[ansyolitico]

Hi.
reading about the chamois I find the various valves including those of distributions, but looking on festo I can't find them

I should do a simple blower with two utilities, in practice I have two seals to get out of air and I would like to command which one to use

if you used a trivial 3/2 but on the contrary? that is the entrance of the air in 2 and the exits in 1 and 3?
being always in exhaust the balance of force between spring, soleinoid and pressure should not prevent the drive.

Thank you.

I think you could do that, but you should consider that one of the two users would always be under pressure and you should predict a flow block before the users (e.g. blowing gun) but if you want to automate you wouldn't even need the 3/2 valve but two solenoid valves (open/closed).

But there are no deviant valves? like those for hydraulic pistons

because the right solution, I think, is a 5/2. or open and closed with two valves.

In your case, with two nozzles u1, u2, the solution could be the one illustrated in the attached image, 5/3 to closed centers, usually used for the operation of a double effect cylinder where the command, instead of manual button as in the image, can be entrusted to two solenoids (electrovalve) or electropneumatic drive with spring repositioning. with this solution when you activate a user, you will also discard the counterpression that may be present in the non-active user.

Wouldn't you want to use two 2/2 valves?
