If any of you have rebuilt or adjusted one of these please let me know. Would like to get some info on it. Thanks

Belay that, I finally discovered it’s called a pressure reducing valve and with that in the search engine it produced enough info to let me know how to bump the pressure up a bit.

Marine06,
They are relatively simple to work on, few parts, the biggest thing that fails is usually the internal orings, or crud gets into it. Most of the time, just a good cleaning will sometimes do it. Soak the regulator in alcohol, then use a cylinder full of air to screw onto the regulator and blow it all out. You can disassemble it, but it's reccomended that you have a regulator tester for it. There's another thread a few pages down from here that was posted a little over a week ago, that might assist you as well.

Thanks Tom,
It’s a new rig so likely doesn't need cleaning. According to the gunsmith at Pilkington (where I got the gun) the regulator likely needs to be bumped up a bit. It’s supposed to produce 29.5 ftlbs and the gun won’t cycle semiauto once I hit about 25-26 ftlbs. I can get the additional power but the magazine won’t cycle in a semiauto mode because I have to screw the hammer spring in too much and evidently when the valve stays open too long it affects the cycling. Or something.
So I’m going to loosen up the hammer spring a bit and incrementally unscrew the pressure regulation screw and see if I can sneak up to about 28.5-29 ftlbs. Shouldn’t need to disassemble the regulator. Or at least that’s the plan.
Cheers,
Rod

Rod,
Yes you are correct, but keep in mind, the diagram that you show, at 65 Bar is for a 10 meter air pistol or rifle. My 12 ft.lb Steyr needs 85 bar to operate at that power level, and the guys that use sub 20 ft.lb guns, their regs are set to around 110 Bar or so for the output.
Just a FYI

Agreed…that’s just a pic of what the regulator looks like. I pulled it yesterday and it looks the same so it should be pretty simple to adjust the airflow. I can’t measure the pressure anyway. I just need to fab a tool to remove the cover which has an annoying two hole security screw.

What I did, was bought a pair of cheap snap ring expander/contraction tool in plier form and used those. Adjustable, and works great. Not expensive either.

I have a set of those and was thinking about trying them but if that two hole screw is tight those pliers might not be able to take much of the twisting force since they’re not made for it. Will give them a try!

Get a set of 1/4" hex driver bits with pin spanner bits!
If you have a friend with a lathe... it is easy to make your Reg tester!
Here is the one I made to service my LP50

The snapring pliers actually worked really well, took the reg out, stuck the plier pins in the holes and turned the regulator to unscrew the cap while holding the pliers steady. Fast and easy. I adjusted the pressure regulation screw about 5 times until I found that it either isn’t the regulator or if it is I’m clueless as to how to proceed so I’m returning the rig to Buck at Pilkington to let him sort it. It’s under warranty so they’re paying for all shipping as well as whatever repairs are necessary.Get a set of 1/4" hex driver bits with pin spanner bits!

Nice reg tester! Would def like to have one for future repairs/rebuilds but have very few friends as it is and none have lathes so I’m on the lookout for one that’s already made.

Well the only ones I have see for sale are across the Pond!!
That is why I decided to machine one up.
Brass is easy to work with...
I use my small benchtop lathe, and Taig CNC Mill.....

Mine got all remade due to cracked plenum, .. but on the plus side added reg tester also on itselfGet a set of 1/4" hex driver bits with pin spanner bits!

When I was working on my Reg tester design....
I Almost went with the Steyr's rectanglar style cutout.... to use their O-ring.
Then realized there was no need CnC that UP!!
So I milled a circular slot to use a standard O-ring I had a bunch of!!!

Actually the original intention was different to start with, due to this crack line formation. This model Steyr may not be suitable for reg pressure pushing higher; plenum wall are actually thin CNC cut out. Any way I made the wall thicker, longer so more air space plenum (slightly larger plenum then original now) on this grafted 7000g aluminium part, along the way just tap a 1/8bsp and seal plug because enough material was there (i didn't face mill the side of the cylinder like original one but left round as it is). In future I can install a reg guage dial also by just boring the gun chassis the size of Guage OD
