How does a regulator work on a gun w/multiple power settings?

[LDP]

Bob that all makes sense when put into words. I will have to see how many more shots I get with my S510 set to a very low power wheel setting. It would be great if someone made a regulated pcp that had an externally adjusted regulator and an easy way to also adjust the dwell so you could change power setting easily and also do it the most efficient way. I will be happy if I get 40+ shots with my S510 power wheel adjusted lower when I need less power instead of the 32 shots I get with it wide open.

It's called an RVA.... changing the hammer spring preload changes the dwell....

Yes but there needs to be an externally adjustable regulator with that. To me that would be the perfect setup if you wanted a regulated rifle for high and low power and also have both tunes on the knee for best efficiency. I know my S510 will partially accomplish this with the power wheel but like you say its not as efficient as a true low power tune is when done correctly like my S10.

For the most part, adjustable regulators need to have the bottle/reservoir drained.... to at least below the new setpoint pressure.... before you can adjust them without damage occurring.... That insures that the Bellevilles are not pushing the piston against the seat, and removes the load from the adjusting screw....

In addition, if you tune for the higher FPE requirement and want a lower FPE for plinking with a high shot count.... all you need do is back off the RVA to achieve that, and at very high efficiency and likely at better shot count, and certainly quieter, than if you also reset the regulator.... The only real downside is that below the setpoint the velocity will spike....

thanks for the input Bob.

Thanks a ton for the comprehensive reply BOB

You're welcome.... It needed to be done, may as well share it....

I think the FX Impact does all of this and has marked settings for each, including the externally adjustable regulator has its own gauge.  Since there is a way to know what each of the adjustments are set to, you should be able to define specific setups and easily switch between them.   Are there any other airguns like that, with all settings marked?
