The Split Body Reduced Bore Trunnion Mounted Ball Valve is designed to provide reliable sealing and efficient flow control in high-pressure pipeline systems. With two-piece or three-piece body configurations, this valve is suitable for large-diameter pipelines and demanding industrial applications. The floating seat design ensures optimal sealing performance, while the bolt connection and RPTFE seal insert deliver long-lasting sealing reliability.

The valve features a split-body design, available in two-piece or three-piece configurations, with a bolt connection for easy assembly and maintenance. An RPTFE seal insert is used along with a stainless steel ring and spring, maintaining reliable sealing while minimizing wear. This construction also reduces operational torque, which is critical for handling large, high-pressure systems.
Recent innovations in valve design include the use of lubricated ball valves, where a special sealant is injected between the sealing faces. This layer improves sealing reliability and decreases operational torque, making it even more suitable for high-pressure, large-sized applications. Bearings mounted on the top and bottom shafts further reduce torque during operation, enhancing the valve's overall efficiency.
