The LPR on spool valve guns... can anyone explain

Actually, right on one of the plates in the marker, whoever manufactured it stamped do not exceed 100PSI - it might have been 150 but it always struck me as odd

they do make lpr's for shockers, and honestly i dont understand why they do not use them. the lpr controls the air to the solenoid, which disperses air to move the bolt. the lowering of this air, makes the bolt softer on paint. remember, the first trixes came without lpr's and had chopping issues... why the shocker doesnt run one is beyone me....

[andreb]

yeah, I've seen those aftermarket LPRs for Shockers... What I didn't know is that Matrix's in the past didn't have LPRs.

Thanx

[magman007]

not a problem, yes the origional matrixes, the old diablo ones, with the pewter grips etc, old *** led's did not come with lpr's, they were later retrofitted, but yea

In a proto the lpr controls the amount of air pressure that is used to move the bolt sail back and forth. A higher pressure will allow the bolt to cycle faster but make chopping more likely. Properly set the lpr will allow the dump chamber to empty completly on every shot, improperly set (to high) could lead to chops, (to low) will give bolt stick, and erratic velocity.

Shockers & LPR's

The addition of an LPR to a Shocker will serve to drop the solenoid's incoming pressure down below the stock levels, however let it be noted that the marker's solenoid already functions at only 90-psi without an LPR (this is a function of the solenoid inserts). This means that you will be able to drop it perhaps 15-20 psi at most.

For that reason it's really redundant to use an LPR on a shocker. I know my 2k4 Tadao'd shocker has never had a problem with the most brittle of tourney paint or chopping issues.

....Not the mention the fact they're FUGLY on shockers.
