Valken V12 QEV Upgrade for Polarstar and Valken V12 HPA Engines

The Valken QEV V12 Upgrade is the latest addition to the line of V-12 Engine performance parts that is capable of increasing the air efficiency, consistency, and poppet cycle time! This QEV (Quick Exhaust Valve) was especially designed to fit and replace the the banjo fitting on the poppet assembly, and because of its compact design it is 100% compatible with Polarstar Fusion Engines. The QEV is also a 360 fitting which means there is no need to worry about aligning the it and sealing it with extra o-rings, just simply remove the old fitting and trim the supply line from the solenoid.How it works: By installing a QEV on the poppet the system the poppet closes faster, and by venting the pressure that is overcoming the poppet seat spring closer to the valve instead of all the way back at the solenoid. This does two things, it conserves more air in the supply line and closes the poppet valve as soon as there is a drop in back-pressure i.e. the bb beginning to pass the crowning threshold of the barrel or exiting altogether.The V-12 QEV is a great upgrade or air stock systems working with limited capacity or high volume support gunners (M249/M240/M60/PKM) that need as many shots per tank as possible
