I have never used one, but Tim @ Mac1 Airguns sells this unit, with a slide check, and says it is good to 2000 psi....http://www.mac1airgunshop.com/product-p/reoute.htmYou do need some way to bleed off the pressure downstream of the regulator, I made a bleed valve like this....There is a Foster on the end of the flex hose where I attach my gauge.... I also use a "tiny" tank so that I don't waste air when testing.... You can see it in the middle of this photo with the regulator attached....Bob
Thank you Mr Sterne. I found one of your posts on another forum that helped. From way back in 2010. the only difference is when I used .054 shim as the post mentioned I never found the setpoint before blowing a 3k burst disc. I used .022 shim and ended up right at 2200psi. If it proves to be unstable I'll try one of those suggested above. Copied and pasted from your post on Airgunhome:First of all, it is necessary to explain what was inside the 2000 psi regulator.... When I pulled it apart, I discovered that there were two different thicknesses of shims and two different thicknesses of Belleville Washers (also known as Disc Springs).... The shims were in a stack in the bottom of the regulator housing.... In my regulator, there were two 0.005" shims and two 0.022" shims.... totalling 0.054" of shims.... My regulator was basically right at 2000 psi when checked with a gauge from a Hill pump which has 100 psi increments.... Cool The disc springs which were on the stem of the piston consisted of a 0.022" thick disc spring on each end, and a total of ten 0.032" thick disc springs arranged in a "single stack" arrangement.... The total stack looked like this: || || ) ) ( ) ( ) ( ) ( ) ( ( Link to the post: http://www.airgunhome.com/agforum/viewtopic.php?t=4564
