Split Body Trunnion Ball Valves: API 6D Class 2500 High-Pressure Isolation

Engineered for Extreme Pressure and Critical Service

This $\text{6}$ $\text{Inch}$ Split Body Trunnion Mounted Ball Valve is designed for the most demanding high-pressure applications in the Oil and Gas, Petrochemical, and Power Generation industries. Conforming rigidly to the $\text{API}$ $\text{6D}$ standard, this valve is rated up to $\text{Class 2500}$ and utilizes $\text{RTJ}$ Flange Ends for superior sealing integrity in harsh environments.

The $\text{3}$ – $\text{Piece}$ $\text{Split Body}$ structure allows for easy assembly and disassembly, while the $\text{Trunnion}$ mounting and $\text{DBB}$ functionality ensure safe, reliable, and verifiable isolation.

🔑 Key Features and Operational Advantages

Split Body ( $\text{3}$ – $\text{Piece}$ ) Design: The body’s modular construction allows for precise machining, superior structural integrity, and straightforward in-line maintenance accessibility.
Trunnion Mounted: Provides mechanical support to the ball, ensuring low, consistent operating torque and reliable sealing under $\text{Class 2500}$ thrust loads.
Double Block and Bleed ( $\text{DBB}$ ): Achieves verifiable isolation. When closed, both the upstream and downstream seats seal the flow, allowing trapped pressure in the body cavity to be vented ( $\text{bled}$ ) for safety confirmation.
Ring Type Joint ( $\text{RTJ}$ ) Ends: Provides a metal-to-metal sealing ring groove, guaranteeing the highest level of joint integrity and leak resistance, essential for high-pressure and high-temperature services.
Side Entry Structure: Standard construction allowing for straightforward installation into critical pipeline sections.
