Slurpy piston valve.

[rna_duelers]

This is my first large(well large for me)Piston valve i named it slurpy because i was drinking one when i was getting the part from the store its not yet complete but it will be soon all i need i 40mm pipe for the barrel and om done.
The valve is made from 50mm PN18 pipe and is in a T is exhausted by a modded sprinkler valve called the samuel MKII.Enjoy.

Any thing i should do to help this valve when its complete?I do have one problem,which is the filling of the cannon were should i place the valve?

I'd mount it in the flow recieving input chamber of your sprinkler valve. My new favorite place.

It's easiest to fill the gun from behind the piston, so that you don't need a return spring on it.

What are you using for a piston? How are you going to attach the sealing face to the piston you plan on using?

The port which is 40mm PVC will be comming about 1/4 of the way into the T and sealing against it.And i wasnt going to use a return spring i got an idea for the filling of it another T before the sprinkler with a male compressor addapter and a 1/4 ball valve.
