one question:

huma regulator gen3 in impact x .25

gauge botlle presure on impact 240 bar--- regulator on 106 bar

gauge botlle presure after some shots on 210 bar---regulator presure go to 104 bar

gauge botle presure after more shots on 170 bar---regulator presure go to 102 bar

gauge botlle presure after more shots on 130 bar---regulator presure go to 100 bar !!!

from 240 bar till 130 bar presure in bootle ,presure in regulator go down for 6 bar

what to check??

i was measure with electronic gauge

It seems there is too much pressure on the stack of spring washers at first, then as pressure drops a so does plenum pressure because the springs have less resistance. I think the regulator needs cleaned and washers lightly greased, and, if it is possible, maybe install one less belville washer so spring pressure is less to see if that fixes pressure stability.

I would also check that the bottle gauge is reading correct pressure. When it shows 130 bar, is that correct? Othervise if you believe you have 130 bar left, you could actually be shooting lower than the regpressure. At some point the regpressure and the digital gauge should read the same, if the bottle gauge is correct. It is not uncommon the bottle gauge can read 20-30 bar to high. You can try to bleed of more air (be carefull to shoot the gun below 100 bar) to like 80-70 bar on the reg, and check what the bottle gauge read. If it still is 20-30 bar higher, I would guess the bottle gauge is not correct. You can also use the gauge on the fill kit to compare the one on the bottle gauge. Just shut off the air suply when filling and check if the bottle gauge read close to the fillkit.

Also if you have recently adjusted the reg, it might need some more shots to get more stable. I know from adjusting the AMP reg on my wildcat down to 115 bar, it slowly got a litle lower to 112-113 over time. But after some hundreds shots it is settled there, and it usually stays within 2 bars pressure difference from a max fill, down to the reg setpoint. I use an edgun digital gauge permanently attached to my wildcat reading the reg pressure, so it should be a pretty accurate reading.

I would check if the velocity stays the same with a chronograph.

velocity go down for some

I would still check the gauges first. And if you have recently adjusted the reg before you started measuring it, I would shoot it some more, to see if it gets more stable by itself. I am not an expert but 2-3 bar drop might be acceptable and normal.

I don't get the question. So you fill to 240 bar. Shoot till it's down to 130 bar. And from all that pressure, you lose 6 bar on the reg? 6 bar isnt that much imo to make sure a big deal out of it. Lots of these gauges will be off few bars. Especially these small gauges. In the real world nothing is exactly perfect. 6 bar loss from 240 bar to 130 bar is nothing. I let my impact sit overnight and it creep like 10 bars. Sometime more. I don't think 6 bar loss will make much difference.

Just a thought here... maybe 100 BAR is at the lowest "working" pressure of that reg. In a perfect world you could have a sensor that could detect exactly 106 BAR and then close the reg., however with just a stack of tensioned springs a few BAR in itself is pretty good.

If I was shooting long range precision I might be concerned. Does this loss of pressure noticeably affect your shooting? Is the POI of 10 shot groups from a challenged distance, say 70 yards any different as the reg pressure goes down from 106 to 100?

so

i am put another huma regulator(i was buy two) and same, exsactly same--when presure from botle go down-in same time with every shot presure in regulator go down for 01-0-2 bar(sometimes more)

also my friend with same impact and same huma reg inside him make same test like my with electronic gauge and result is same, so 3 huma regulators show same results---with every shot presure in regulator go down for 0.1-0.2 bar--sometimes more than 0.2 bar

then i am put back my fx regulator--and repeat all proces

result is : from 230 bar till 120 bar diferent in bar is 1-2 bar in regulator, my friend pani sd also make that like my and his result is total same---diferent in regulator presure is 1-2 bar

i am buy huma reg just if i need to shoot with regulator presure over 150 bar-stupid choice

why stupid? becouse we are make tonight with diferent arrange position of springs presure that what we want, if we want with fx regulator more than 150 bar we can do that without losing bars during shooting

thank you everyone on help and sorry for my bad english but big thanks and here always can find help

regards from south europe from montenegro
