balanced push to open valve

Unread postAuthor: wyz2285 » Tue Oct 25, 2011 1:59 pm

Our member warhead052 had asked me to do a tutorial about the valve I showed here, so I thought maybe it´s good to share this design, as it´s very simple to make, and can be used for many purpose such as pilot or firing valve even can be mod to a 3-way.
(actually I got the Idea from this topic)
I can´t fing the exact model of my push in fitting, but this one will work, for 6mm tubes
(sorry the images aren´t in order)

you should be able to see a o-ring inside it, perfect for 6mm tubes.

polish it nicely and drill 4 exhaust ports, 3mm ID max and cut 4 gaps, about 4mm deep

I put a section of a ballon to protect the valve stem from dust.
finished
