how does a qev valve work?

Unread postAuthor: Tijn_416cs » Sat Mar 12, 2016 4:51 am

I'm making a semi auto airsoft gun, and I heard alot about quick exhaust valves.
I want to use 12gram co2 cartridges and I thought about having a set up like 12G co2->Qev->schradervalve or blowpistol
would that work? Thanks

When the control valve exhausts air from the exhaust valve inlet port, the Buna-N poppet shifts to seal the inlet port and open the exhaust port to the cylinder. The pressurized air is allowed to exhaust directly through the exhaust valve to atmosphere.
