These valves use a lot for air for their extreme performance.
Larger the capacity of the tank, higher the number of shots and more consistent results.
If you have your own tank with M18 x 1.5 threads, then it would be a direct fit.
Note: The "Extreme-Flow Valve with Assembly" is for those who are using slugs, casts, round balls etc in .25 configuration.
If you are using heavy pellets in .25 cal then our "Hi-Flow Valve with Assembly" is all you need.

This Extreme-Flow Valve does ship with a custom hammer spring and replaces the factory hammer spring to obtain better results.
You would have to increase the hammer weight, so we've discounted the price for the hammer and added it as a combo.
You may choose whichever hammer you would like to have, Steel or Brass.
Kindly mention it in the notes when the order is placed.
If you forget to mention we will ship whichever we have in stock.
We have tested both the hammers on this valve and the results are outstanding so do not worry about the performance.
(Older version of Extreme Valves)
The best tested performance for this valve is from 3650 PSI to 2900 PSI (Make sure your bottle supports this pressure)
(Newer version of Extreme Valves)
Tested performance for the newer extreme flow valve is from 2800 PSI to 1500 PSI.
The valve can easily handle 3650 psi, but the initial shots are going to be at less power when filled to 3650 psi.
(NEVER FILL ABOVE THE WORKING PRESSURE OF YOUR TANK OR VALVE) (LOWER WORKING PRESSURE TAKES PRECEDENCE)
So, we recommend filling to the best tested performance of 2800 psi on these newer valves.
The order ships with the below 5 items and the price listed is for the combo :
