I don't need it be relieving. Downstream pressure will be filling the firing valve, and there's no reason for me to need the ability to change pressure settings with the firing chamber pressurized.

Sorry for the necro, but I just wanted to clarify. Something like this will work for my desired application?

Thank you. This helps immensely. I had a feeling it was something simple that I just wasn't getting.

Hey, guys. I had some question about air pressure regulators. I've spent a couple of hours today researching air regulators, but I still can't figure out what what I'm looking for is called. I need a pressure regulator that, when the downstream pressure has been maxed out, closes itself and doesn't ...

Thanks a ton for the help, guys. This pretty much perfectly answers all my questions and concerns. If anything else pops up I'll post it here.

I'm planning to build a high pressure (in the 300 to 400 PSI range) pneumatic that fires 1/4" steel shot sling shot weights. Sorry if this is the wrong section. I know this is with 1/4" ammo, but it seems that the BB gun section is filled with BBMG/Vortex/expensively wasteful full auto set-ups. I fe...

My apologies to revive a relatively old topic, but I feel this is a decent enough reason... I'm searching for something with a ~.25" ID for 1/4" steel shot sling shot weights (with my caliper I measured them at .2485"). I stumbled across this on McMaster: http://www.mcmaster.com/#brass-tubing/=75d6w...

First off, I'm really sorry if what I'm asking for can be easily found elsewhere. I've spent about 15 minutes searching the site and combing stickies. I haven't found anything. What I'm asking is, is making a homemade DCV valve possible and/or practical? I'm hoping to emulate the function of this va...
