Key Specifications / Features

Model No. : 181302002

Double-block-and-bleed trunnion-mounted ball valve, integrated dual-ball construction without an intermediate bleed port. Support brackets are mounted at the valve bottom to bear the valve weight and reduce pipeline load. Worm gear operation provides stable torque for opening and closing. Full bore design reduces medium pressure drop. Forged valve body ensures structural integrity under high-pressure service conditions and is widely used for pipeline isolation in energy process systems.
