FX Regulator - adjusting pressure

[Widget23]

FX Royale 0.25 with the FX regulator (prior to the "AMP" version). Regulator was at 128 BAR (where it seemed to drop off the regulator). I am trying to get the 33.95 grain JSB Heavy Mk II up to 830-840.

At the 128 BAR, I was shooting the LIGHTER 25.4 grain at 874.4 avg, ES = 12.08, SD 3.87

I want to adjust the regulated pressure higher. I put an allen key in the center of the nyloc nut. Then I turned the nyloc clockwise 1/2 turn while holding the allen key stationary. The pressure seemed to only go up maybe 3-4 BAR. Is that normal? What am I doing wrong?

Is there a rule of thumb that says turning the nyloc X amount increases the regulator pressure Y BAR?

ALSO: Once you adjust the pressure, should you fire a number of shots to let the regulator settle in at the new pressure?

I'm pretty sure it's counter clockwise to increase reg pressure and clockwise to decrease. Don't quote me on that but I'm almost 99% sure. Also, never decrease reg under pressure or you could damage something or blow an oring. Yes fire a few shots once done. Good luck

Should take some shots to settle in but usually a half turn would bump it quite a bit. 10-20 bar if i had to guess.

And I think Redick is right loosening the nut raises the pressure.

Counterclockwise!!!! Clockwise with pressure in the bottle can break your gun!!!!

Also be careful how far out you back the screw out. It shouldn't go much past flush or the upper o-ring will move into the threads, get damaged and even blow out. This is a common cause of leaks.

Regulator in Royale has to be removed to adjust so no worries about adjusting with the gun aired up.

Yes, I need to take everything apart to get to the regulator. It's not externally adjustable.

TrapdorSpydr says: " Loosen knob – raise pressure or tighten Teflon nut -raise pressure. Both actions move the valve away from closure. "

Here I am assuming by "Teflon nut" it means the nyloc nut? It's the only nut on the regulator.... So I tightened the nut, i.e. turned it clockwise while holding the allen key stationary. So you guys are saying turn the nyloc nut CCW?

 

[Glem.Chally]

Yes ccw will bring the reg pressure up. From the impact manual but same idea.

Ernest put out a few great vids on the regulator and adjusting it. Here's a couple. Thanks again Ernest for making these how to's.

When i bumped the reg in my royale, i held the hex and turned the nut clockwise. But, 1/6th of a turn, one flat of the nut took me up 15 bar. On half turn seem like it would be way too much. Seems like i read it could get damaged above 160 bar? Id try backing it off a quarter turn.

FX Royale 0.25 with the FX regulator (prior to the "AMP" version). Regulator was at 128 BAR (where it seemed to drop off the regulator). I am trying to get the 33.95 grain JSB Heavy Mk II up to 830-840.

At the 128 BAR, I was shooting the LIGHTER 25.4 grain at 874.4 avg, ES = 12.08, SD 3.87

I want to adjust the regulated pressure higher. I put an allen key in the center of the nyloc nut. Then I turned the nyloc clockwise 1/2 turn while holding the allen key stationary. The pressure seemed to only go up maybe 3-4 BAR. Is that normal? What am I doing wrong?

Is there a rule of thumb that says turning the nyloc X amount increases the regulator pressure Y BAR?

ALSO: Once you adjust the pressure, should you fire a number of shots to let the regulator settle in at the new pressure?

you did it the right way but you over did it. how are you checking the regulator pressure?

I am using a chronograph and plotting where the speed begins to fall off.

I'll go back and make a smaller adjustment and see how that works.

without a regulator tester it will be very difficult to adjust it properly since the Fx regultor usually starts creeping when it is over adjusted. Still in my experience 1/8th of a turn will give you around 10 bars. Hope it hepls.
