High Pressure Trunnion Ball Valve Manufacturer
ZONCIC manufactures high pressure trunnion ball valves for oil & gas pipelines, petrochemical plants, LNG terminals, refinery units and critical industrial shut-off service. Our trunnion mounted ball valve solutions are available in Class 600, Class 900, Class 1500 and Class 2500 pressure ratings with API, ASME and project-specific configurations.
High Pressure Trunnion Mounted Ball Valve for Demanding Service
A high pressure trunnion ball valve is designed for stable sealing, lower operating torque and reliable shut-off under severe pipeline pressure. Compared with floating ball valve designs, the trunnion structure supports the ball from both upper and lower positions, making it suitable for larger sizes, higher pressure classes and critical isolation points.
ZONCIC provides high pressure trunnion mounted ball valves for project buyers, EPC contractors and industrial distributors who require dependable valve performance, material traceability, pressure testing and export-ready documentation.
