valve differences

[bigboy]

what is the difference between a pin valve and an on/off valve on a co2 system?
Can you take co2 off of the gun when not using it, even if it is still full?
I also heard that co2 degrades the seals and o-rings, is this true?

Thanks.

A pin valve has a little pin which allows the gass to escape from the bottle when it is screwwed in.

An on off has a tap so you can open and close the valve when you want.

both valves allow you to take the bottle off the gun when you not are using it

an on off is better though cos you can remove the
bottle with less wear to the o-ring
