Adding A QEV to your Odyssey RPM

Please note; The Old Model RPM already has a QEV hidden under the Ram Cap, this page was made for those of use that have the New Model RPM. If you are not sure which Odyssey RPM you have check out this link;

How will a QEV help?

QEV stands for Quick Exhaust Valve. QEV’s are used in paintball to release backpressure from the markers Ram that builds up during the return cycle (as the Ram goes back to its rest position). This can in turn reduce the cycle time of the marker by not building up unnecessary back pressure and reduced cycle time means a higher rate of fire, thus increasing firepower.

A picture of the Old Model RPM Ram with the Ram Cap removed to expose the QEV that is hidden under the Ram Cap. Adding a QEV will not help the Old Model RPM as it already has one installed. This is not to say you couldn’t upgrade the QEV to a more popular name brand or better quality.

Here is a close up picture of an Eclipse QEV installed on my New Model RPM marker. The New Model RPM does not have a removable Ram Cap as the female or cup side of the Ram is a one piece design. I chose the Eclipse QEV because of its small size and proper thread design, be sure to use the QEV designed for AutoCockers on Odyssey RPM as the RPM’s Ram is threaded the same as an Autococker.

Installation

In my case the installation of the QEV is easy, because of the Autococker LPR Modification. I used a very small 0-ring that had to be stretched to fit over the threads on the QEV to help seal the QEV to the Ram. The 0-ring does a pretty good job of sealing the QEV (keep in mind the QEV only needs to seal off about 60 to 80 psi when used with the LPR modification), so there is no need to over tighten it down on the ram. Simply tighten it until it is lined up properly and slightly snug on the 0-ring, a wrench is not needed for this application when used with the LPR modification. If you add a QEV to a marker using only the HPR then you may want find a better way to seal the QEV to the Ram (I’ve never done this application, so you’ll need to come up with your own method). I used 5/32 Intimidator hose, other RPM owners have used Autococker hose (one size smaller) without any problems.
