Split Body Ball Valve

A split body ball valve is a full-bore isolation valve featuring a pressure-retaining body divided into two or three pieces bolted together along a flanged joint. This multi-piece architecture allows the valve to be split open during routine shutdowns, providing direct access to internal components like the ball, seats, and stem seals for quick in-line maintenance instead of requiring total valve replacement. Depending on the application, these valves utilize either a floating ball design for low-to-medium pressures or a trunnion-mounted configuration for high-pressure double block and bleed (DBB) isolation. The internal seating is highly customizable, employing bubble-tight polymer seals (like PTFE) for ambient utility services or hardfaced metal-to-metal seats for abrasive, high-temperature environments. Piping contractors and refinery maintenance teams can significantly extend operational lifecycles and reduce replacement costs by importing certified split body ball valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
