Attention Valve option only for customers who already have a Rocketkey or FullPowerValve the Valvepin can still be used. !!!

For comparison, a Rocketkey has an output of 10 -13 joules
Our set-up has an output of 20-30 joules and you have about 10-15 rounds depending on the ammunition


Since Co2 is very dependent on temperature, we recommend storing the Co2 capsules at room temperature, as the Co2 expands and the pressure increases!

Attention, strong performance increase! Not suitable for paintball. Only suitable for the 7,5 joules (F version)! ! !

The acquisition and possession of this export valve is free, installation is prohibited in Germany due to the increase in performance and leads to the loss of warranty claims.
