Floating ball valve design feature:

Live loaded gland flang
Live loading is designed to provide gland load retention, compensating for expected in-service consolidation of packing. A set of belleville spring washers are used on each gland stud to help exert a continuous compressive force on the gland follower flange and therefore reduce fugitive emissions from the stem packing. ARITA standard belleville-spring washers are protected by a weatherproof cap to keep them free from environmental contamination, resulting in a long stable life.
