Home Defense "High Impact Valve" for the Roscoe revolver

With this Exort valve, the Umarex HDR 7.5J standard version, becomes just as powerful as the open 11J version.

Basically, at least 16J+ are possible with this Powerkit.50. To achieve a higher power of up to 30J depends strongly on the ammunition used as well as the correct temperature.

Technical details:
- GOLD ELOXIDATED
- No more valve needed in the pressure chamber
- High strength special aluminium
- Increases the power up to 20 joules! (depending on temperature)
- Longer valve opening time, larger gas volume
- Reduced cool down effect
- Valve pin made of aluminium for better sliding and protection of the sealing ring

Installation can be reversed at any time.
For comparison:
A Rocketkey brings an output of 10 -13 joules.
This set-up brings a power of 20-30 joules and you have approx. 10-15 shots depending on the ammunition.

Scope of delivery:
- 1x pressure chamber insert
- 1x valve pin

Attention strong power increase! Not suitable for paintballs. Only suitable for the 7.5 Joule (F version).


The purchase and possession of this export valve is free, the installation is forbidden in Germany due to the power increase and can lead to the loss of warranty claims.
