Valves and Regulators

At Arrow Precision, skillful design, careful choice of materials and precision machining are all combined to produce the safest, most reliable paintball valves available.

There is provision for safe release of gas from the cylinder in the event of unintentional unscrewing from the cylinder of the valve or regulator.

The two milled sections on the male 5/8th UNF bottle thread has been designed to form a channel to allow controlled release of the
contained gas.

The two channels are opposing each other so any resultant forcesgenerated by the releasing gas are equal and opposite and hence cancelled out.

The male 5/8th UNF bottle thread has been designed over the required length (2D) to engage with female cylinder valve so there is more turns to actually remove the units.

This is intended as a secondary safety element so that even with gas escaping from the safety channels, a user could not fully unscrew a full cylinder- causing a projectile cylinder.

The escaping gas should also act as a very good indicator to a user that something is wrong and prevent further unscrewing!
