Regulator acting weird!!!!
I have a reg tester here with me. Borrowed from a friend. I took the reg apart and cleaned the Belleville washers. I cleaned all parts with alcohol and allowed them to dry. I then used high pressure air to blow away any debris. I never turned the set screw (until later) and when I reassembled the reg, the regulated air was 100 BAR. I then started making small turns (1/16th to 1/8th turns, counter-clockwise) on the set screw. I got the regged pressure to 120 BAR and it seemed okay. I would quickly loosen and tighten the bleed screw on the tester, simulating a shot and the needle was quick to go back to 120. But I want 130 BAR (25 caliber). So I turned the set screw counter-clockwise about an 1/8th of turn and I placed reg back in tester. The reg pressure is equal to the supply pressure (200 BAR). I have done this no less than ten times and I finally got it set to 140 BAR (I thought) but as I brought the supply pressure up to 200 BAR the needle of the gauge of the tester starts easing up until the reg pressure is equal to the supply pressure. The only o-ring that I haven’t tried is the one on the set screw itself. I was meticulous about not losing any parts or orings. I am baffled. Anybody got any ideas? Other than “I should’ve just left it alone”? lol Thanks for any feedback. Kevin

Every time I read a post like this it further solidifies my mantra… buy new guns.
Thanks, Mr.newbie. Yes, about got it put back togther. I’ve already pumped the tube back to 200 BAR. Wasn’t that bad. I would have got it oumped faster if my male foster fitting wasn’t so long and doesn’t work well with my EDgun probe. The bottom of the probe won’t reach the bottom of the male foster so I use generous amounts of pink teflon tape. But still, leakage. I have a new male foster on the way but I fear that it will be the same. But I can shorten that sucker (the male foster threaded part) with a Dremel cut off and then dress it up. If I can get that brass threaded end of the EDgun probe to touch the inside of the male foster and then apply pressure with wrench, I can cut the leak off. The brass will seal on the steel foster innard, (for lack of a better word.
If anything good has come out of this……I know the ins and outs of the EDgun regulator. I was amazed at the size of the Belleville washers when compared to some other Belleville’s that I had in a butter dish from another brand of airgun. I was impressed.
Congratulations, you got her working again…
The valve is at the end of its stroke.
Just get a normal Washer, 1 mm thick.
Place it like ()()()()()()I
You will have to adjust the reg again, but it will reach 140 bar.
1mm, NOT thicker.
Regards Robert.
That is just what I did. found a washer (.003 inches thick) that Weihrauch puts on the inside of their HW95 pitons. After opening the hole up and polishing, it looks as if it was made for the reg. It fixed my problem!!!! I have been working on it since last night.
I am a chronic tinkerer. Sometimes my tinkering gets me in jams. But the satisfaction of getting unjammed is very great.
I appreciate all of the replies. Especially the one clam shells and so forth. My skin has grown thick over time. I can now chuckle at what used to would have hurt my wittle feelings. lol (The last paragraph wasn’t directed to you Robert). I wish all forum members an exquisite Merry Christmas!!!
my 25 cal regulator has been installed this way ()()()()()()).
Some reg have problems to go above 140 bar.

Meanwhile, I try to fix something that will raise the stack back to where it should be. I KNEW that I shouldn’t have started out with 400 grit emory. I probably removed a thousandth from each washer. MY DIY days are at an end. lol And it looks like my squirrel season is at an end as well. Good thing I metal detect.
Thanks for the reply KS! And Merry Christmas.
Most paintball shops carry parts to repair regulators. They may not have the exact same Belleville washers, but they may have some shims, they come in a few different thicknesses.
For example a 10 thous shim may add 50psi, and a 30 thous to add 100psi another washer adds around 250psi. A general idea, not exact numbers.
If it were me, I would just go to the local hardware store with parts in hand, and find a stainess steel machine washer that fills in the 10 thousandths or so you polished away.
Replace any orings that separate the main air tube from the output chamber…I’m no expert (well I think I know what I’m typing about :rofl: ), but I would not replace those Belleville washers, I would think your polished up washers on a little tightening up spacer would perform just as good, if not better than a new washer stack.
Polished the clam shells. People love to screw with shit.
I didn’t catch that you polished the washers. That is your poroblem. Those washers are incredibly sensitive. I had one set upside down on my Lelya. The gun would shoot fine until I got to 160 bar. Then the FPS would jump from 800 to 880 until I got down to 100 bar. I pulled the regulator and found one set was upside down. When I put them right the regulator functioned perfectly. Call Tony and order new ones and don’t polish them. Ed knows what he’s doing. He has forgotten more than any of us will ever know.
Yes, it is installed correctly. But yes, it is an appropriate question, as I am new to the EDgun regs. I have replaced all of the regs Orings and lubed them sparingly. I still get the same results. I can only get the reg set to 100 BAR and it functions correctly. The odd thing is: I didn’t mess with the setting at all when polishing and lubing the Belleville washers. I have narrowed it down to this: I have removed to much material from the Belleville washers. That is all it can be. New O-rings. Meticulous about blowing all dust out. Heck, I treated it like a sterile surgical instrument. I need to find a thin piece of metal that I can use under the Belleville stack and then I can rule that out. I mean, all of the evidence points to my screwing up the bellevilles. The reg was set at 130 from the factory. And I made sure not to touch the adjustment screw OR the cap screw which covers it. I left them alone because I wanted to keep my reg at 130 BAR. Does anyone here have 12 new Belleville washers for the EDgun?? I’ll gladly pay you via Paypal or money order. I have a good BOI record on the Yellow forum.

Kevin before we dive into the problem are you 100 percent sure that you have the regulator inlet (screw side) down and the outlet (flat side ) up (towards the gauge) in the regulator tester?
I know it seems like a dumb question but I might know a guy who tested his regulator upside down and got weird numbers too 😳

This male foster works, it has a nylon insert that makes the seal with the probes threaded end.
