This is NOT true ... A balanced valve set up can be Super quiet for the power produced .... have personally built and tuned quite a few PCP's with these valves and when set up correctly, they IMO honestly don't need an LDC unless wanting really quiet !!
Asking out of absolute ignorance here:
Your pellet weight is just controlling your valve dwell. Light pellet, air still coming out barrel after Elvis has left the building. Heavy pellet, making the most out of the air. Yes, you should try to control that with reg pressure, hammer spring and valve if your gun has that option. You do have some wiggle room if you don’t get all obsessed about it and still have a good shooting gun.
Exactly. Although I was very pleasantly surprised by how a very small adjustment of my valve tightened up my slug groups while not negatively affecting my pellets.
Unfortunately what that very small adjustment showed you was just how fine of a line your gun and barrel system is walking in order for it to shoot well. That’s why some abandon the platform.
Case in point for many of these PCP's starting to use balanced valves .... Without a miens to mechanically limit poppet lift ( Buffer ) these valves poppet are allowed to just full lift off the seat
That’s why when all you guys were going valve crazy over on GTA years ago, I jumped on board. It didn’t take me too long to jump right off that moving train when I became concerned about wearing out the threads on my guns from having to take them apart so often. I abandoned my own cobra valve but stuck it out with a JSAR SS valve for a while on one gun before I just finally regulated it. Complex valves require a whole new level of understanding and patience. Especially if you build your own.Case in point for many of these PCP's starting to use balanced valves ....

It was a major fault IMO when viewing a URAGAN 2. The factory had followed nicely the general design of a pressure feedback design, but OMITTED an miens to control poppet lift .... End result is no mater how you adjust HST or pressure the valve trends to just blow wide open upon discharging.
Yea you may find a place in the adjustments that is better and if it is worse either side of that place ... It is telling the system as a whole is way out of correct balances of Hammer weight, Spring rates, Venting size, Balance chamber specs etc ...
IMO ...
It keeps me from being bored......lol
Yes, but once you find that 110gr of Triple 7 and bullet X is the magical combo for your gun, nothing ever changes. No matter how many times you clean the gun or take it apart. Airguns and bullets can be next level fickleness.
I haven’t been in communication with them since I bought one of their adjustable Raptor regs for my RTI. That was years ago. Then and before that when I spoke to them on the phone, they were cool. I have no clue what’s going on there now.
