When removing valves from composite pressure vessels use extreme care and be sure to protect the composite overwrap from harsh fixtures and tool handling!

When removing the valve, do not clamp the cylinder with a hard jaw vise. A soft strap wrench or soft conformable vise must be used to grip the composite cylinder when removing or reinstalling the valve. A hard vise can severly damage the composite overwrap and reduce the strength of the cylinder.

CAUTION!
Some manufacturers of paintball valves apply a small amount of Loctite to the valve threads before screwing the valve to the cylinder. This practice of 'sealing' the valve to the cylinder unfortunately makes it extremely difficult to remove when it comes time for reinspection (hydrotesting). We do not condone the use of Loctite and strongly recommend all paintball valve manufacturers refrain from its use.

WARNING!
NEVER APPLY A FLAME TO HEAT THE CYLINDER NECK TO LOOSEN A 'DIFFICULT' VALVE ASSEMBLED TO THE CYLINDER. THIS PRACTICE WILL DRASTICALLY REDUCE THE STRENGTH OF THE ALUMINUM LINER RESULTING IN A SIGNIFICANT SAFETY HAZARD.


Be careful to inspect the exterior of the composite overwrap for any signs of damage (cut, broken or abraded fiber, unraveling, or burned/charred areas). If any damage is visible, consult CGA C6.1 for guidance on repair or condemning criteria and procedures.
