Trunnion Ball Valves
Trunnion ball valves are quarter-turn valves used to begin or stop the flow of a media in a pipe.It has a “free floating” design, so the trunnion type is a design change. Within a valve the ball links to the stem on single end and on the other end a shaft known as the trunnion. Due to this design change, the ball is strongly place.
Trunnion ball valves are very versatile. They are used in lots of different kinds of industries because of their customizable specs. For example, Trunnion ball valve specs O-rings and fire-safe stem packaging that stop leakages. It also comes with stainless steel sealant injection fittings for seat sealing or emergency stem. They are largely used in oil, petrochemical, chemical and gas, LNG and hydrocarbon industries.
These valves are perfect for big scale high presure applications and compact, low-temperature conditions.
