Unread postAuthor: UHU » Mon Oct 01, 2012 12:08 pm

Hello there.

You would need two different tanks to do that and they would have to have ball valves on them to let the air into the piston.

You would need a large air source tank and a smallish air chamber. A 3-way DCV or multiple ball valves would be needed to pilot it.

That's not a problem. That's a feature.

If you don't want to dump all the air, don't use a piston valve.

... or use a piston valve, but use a momentary pilot valve like a hammer valve.
