How many times can an autococker cycle per second?

[nicad]

pbjosh-
wouldnt it be easier to test the close times MY way? MuHAhaha!

MY way..

saves paint and air.. and the environment! well.. maybe.. ah what the heck.. screw the environment!

Josh....

What inline regs can keep up with the Race @ 14bps?

[nerobro]

A unireg should come close.. given that the AIR can keep it up at 16bps (Accordign to the oddyssey paintball videos of the hyperframed AIR vavled mag) The Stabilizer can handle 20 bps (or thereabouts according to the AGD gun dyno) thanks glen for that magic peice of hardware ;-)

and... let's hope that the Rt inline reg is actually going to show up sometime.

I have a angel minireg and it's horrible. It fluctuates madly... I need either a Stabe or a Sidewinder.

Nothing against the guys at Pro Paintball, their gun is excellent. You can only do so much with the WDP minireg design though.

The Stabilizer can easily handle 14 bps out of any paintgun that I know of and do it with a VERY narrow range of variation. Just as long as the input flow and pressure into the reg is sufficiently higher than what is needed buy the gun.

Glen...

When you say the Unireg is a 35:1 rated regulator, and the Stabilizer is a 70:1 rated reg, how did you test that?

I really don't like to be contradictory to the AGD gun dyno but do believe that it's results given for a test of the Stabilizer to be just a tad on the conservative side.
I have a rig here that I built in 1991 called the Grinder. Simply put, it is 3 closed bolt guns (Hurricanes actually)mounted side by side in a box that are crank operated and cam lobe activated. Each has it's own automation system but a single Rock reg supplies the air control for all three guns and a single Stabilizer controls the main supply to the whole rig from a single large CO2 tank. When I get that baby going, it is easy to reach the 30 bps range with all three guns spitting paint and The Stabilizer has never had a problem keeping up. Even with CO2, which moves a bit slower than compressed air does.
As I've stated before, my ways are quite old fashioned but I've seen the results for myself and repeated it numerous times. Therfore it leads me to believe that a 20bps capability for the Stabilizer is significantly understated.
Can't wait to see how test comparisons come out against the RT vertical reg.

Simple mathematics. surface area of the plunger compared to port diameter of the valve seat.

Glenn,
When watching the test, I think the issue was that the stabe can hit that range before only partially recharging to the origional pressure before the next shot.

Shootdown or starvation are not always the next logical step. On spring/hammer driven markers, there is a fixed force being imparted on the valve. However, as the pressure within the valve drops, the force resisting the hammer lessens, valve dwell/WO time increases. I haven't reviewed this thread in awhile. If this has been disputed, by all means rip me to shreds.

As for buying an RT vertical reg... I'd be hard pressed to give up my stabe... it depends on whether the input is on the bottom or not. :P

[nicad]

"RT vertical reg"... whats this yall are refering to? have I been sleeping too long?
Arent most all of AirAmerica's vert/inline/main regs built from AGD reg parts?

Also Glenn- the ratio you mentioned.. doesnt that depict how much the reg's output will vary based on input pressure?
ie- 70:1 means for every 70psi variance on the input, 1 psi variance on the output-- due to the air pressure on the surface area of the exposed valve seat.

I understand what you are saying and your depiction of the valve operation is right on. Also, correct about starving not always being the case. However,higher pressures and flow potential to the input of most regulators, does in fact increase the output flow rate potential of the regs valving. On a two stage regulation system, the cure for starvation is often to increase the output pressure from the primary reg. Style and positions of fittings, hose length, the air passages in the gun itself, etc etc. all have a particular bearing on recharge rates and often times more so than the reg itself.

Something to consider about the regs with the input line on the bottom: That style of regulator relys on the regulated air to close off the valve instead of backing off the plunger and spring to let he valve close. Much better suited to the hydraulic or liquid environment that they were originally designed for. A liquid, that cannot be compressed can hold the valve closed more effectively and consistently than a flexible volume of air/gas.

I think you are right about the parts. The biggest advantage of the RT reg over the older versions is the much larger plunger diameter. Now 3/4" as opposed to the original 1/2" diameter plunger.

Also Glenn- the ratio you mentioned.. doesnt that depict how much the reg's output will vary based on input pressure?
ie- 70:1 means for every 70psi variance on the input, 1 psi variance on the output-- due to the air pressure on the surface area of the exposed valve seat.

That is exactly right and the varience is inverse. Meaning that as the input supply pressure goes down the regulated output goes up and vice versa; in that ratio equal to the dimensioning.

Glen,
Does this apply to the Govnair/WDP style of reg?

It applies to any pressure control device that I know of.
You just can't get any more air out of a reg than what you put into it. :)

Most definitely noted.
