ABSTRACT:
A valve, possibly for use in a paintball marker, has a longer threaded portion that insures a canister that engages the valve must undergo many twists to become unscrewed from the valve. Alternatively, the valve has an elongated threaded portion with gas bleed channels that extend along a substantial portion of the threading. Still alternatively, the valve may use visual markings along the length of the threaded portion to indicate to a user that the canister is being unscrewed.
