TRUNNION BALL VALVE - STEFFENINI

Steffenini Trunnion ball valves are a high-end industrial ball valve series, designed to API 6D standards, specifically for high-pressure and large-size pipeline systems (DN150 – DN600 and above), commonly found in the oil and gas, chemical, and energy industries. They differ from floating ball valves in that the ball is fixed by a trunnion, reducing friction on the seat and increasing durability during high-pressure operation.
