| I would not use any valve that has a "venting channel".
The few that I have seen have been BADLY carved with a grinder and are clearly unsafe. They also render anti-siphons, and siphons useless.
According to Catalina, tank valves should not be threadlocked. Threadlocking at 20lbs is the same as not threadlocking at 45lbs. The only difference is that threadlocking can ruin the threads, and render the safety vent useless.
The irony is that threadlocking the valve makes it MORE likely to be a deadly rocket, as seen with the sad story 3 years ago of the lady that was killed by a threadlocked co2 tank. (The loctite had clogged the safety vent). They used NPS and discovered that
NPS was using loctite for the simple reason that it meant they didn't need to properly torque the valves. Often just handtightening!
IMO, you should follow manafacturer specs, and not threadlock. But properly torque to 45lbs, and avoid valves with "channels".
