Ahh i got it, so need both its not a replacement for qev. Thanks so much!

Ok, great. The idea im trying to build is a HPA powered Nerf Rocket launcher. Load a rocket, "pull" trigger releasing the air through the QEV launching the rocket. Then simply load another rocket and repeat. No need to "charge" the system because the HPA tank is a constant flow only restricted by th...

QEV interests me, so can I use one with something like this? https://www.amazon.com/Interstate-Pneumatics-VBT44-Button-Female/dp/B0098W48HW/ref=pd_sim_328_5?_encoding=UTF8&pd_rd_i=B0098W48HW&pd_rd_r=0QZQ8FPGXS4R15CV3BQZ&pd_rd_w=Xhg8E&pd_rd_wg=HOOT9&psc=1&refRID=0QZQ8FPGXS4R15CV3BQZ like the idea of ...

Welcome to the forum! Are you looking to keep the electric actuation of the sprinkler valve or to modify it for manual actuation? Im considering both options, as i understand the manual will release faster, but if the electronic is acceptable might leave that. Being new scared that hooking an hpa t...

Hello, im a cannon noob, looking to build an air cannon for nerf rockets for airsoft. Been looking at various designs. Leaning toward 12 gram C02 as a power source but would much rather run and HPA 3k psi tank with regulator. My question is about using the sprinkler valve that everyone uses. How muc...
