The ESI 3 PIECE Trunnion Ball Valves are high-performance valves designed for both standard and cryogenic services. Built as robust 3-piece trunnion-mounted designs, these valves maintain full port flow paths to minimize pressure drop, and are manufactured primarily from forged stainless steel (A182-F316) or carbon steel (A105).
The cryogenic version is equipped with an extended bonnet, providing increased safety by distancing the actuator or operator from low-temperature fluid zones. Available end connections include RF and RTJ flanges (ANSI Class 150–2500) and butt welds. Fire-safe and certified to major international standards, these valves are automation-ready for gear, pneumatic, or electric operation.
