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 bolted connection that enables easy assembly and maintenance. It uses an RPTFE seal insert paired with a stainless steel ring and spring, which maintains reliable sealing while minimizing component wear. This design also reduces operating torque, a critical advantage for large, high-pressure systems.
Recent innovations in valve design include the development of lubricated ball valves, where a special sealant is injected between the sealing surfaces. This sealant layer improves sealing reliability and reduces operating torque, making the valve even better suited for high-pressure, large-scale applications. Additionally, bearings mounted on both the upper and lower shafts further reduce torque during operation, boosting the valve’s overall efficiency.
