trunnion ball valve

Trunnion Ball Valves are heavy-duty quarter-turn valves designed with a mechanically anchored ball that is supported by upper and lower trunnions, allowing reliable operation under high-pressure and large-diameter service conditions. This design minimizes operating torque while providing bubble-tight shut-off, exceptional sealing performance, and long service life in demanding industrial applications. Commonly used in industries such as oil & gas, petrochemical, LNG, pipeline transmission, power generation, chemical processing, offshore facilities, and industrial manufacturing, trunnion ball valves support process safety, operational reliability, reduced maintenance, and efficient flow isolation by delivering dependable shut-off performance for high-pressure, high-temperature, and critical process applications.
