When you tighten the cap, it allows gas to flow through. When you loosen it, it stops the gas flow.
Do you know how a pin valve works on a HPA or co2 tank? When he center pin on the tanks valve is depressed, it releases the gas. On the Omens on/off asa, as with all on/off asa(excluding smart parts) When you screw in the nob it will open the valve to the tank but pushing onto the pin on the tanks valve. When you unscrew the Omens nob, it will back out on the tanks valve and stop the air coming out of the tank.
When you have a normal asa, it just pushes in on the as you screw the tank in.
