A man should never complain that the valves they use are too tight
I would take the loose ones and throw them back in the bin they came from ....those hussies!
In all seriousness just play with the valve handle a little bit longer it will open up smoother for you. Most valves are self lubricating especially after pouring a few beers through them
make sure your valve is cleaned after use ...nothing worse than a unwashed valve
Ok, I'll stop now (and let someone else chime in :cross
