Reduce Bore Ball Valve
28 products found
A reduced bore ball valve (or reduced port ball valve) is a quarter-turn rotary valve engineered with an internal flow path diameter that is smaller than the nominal diameter of the connecting pipeline, typically by one or two standard pipe sizes. By restricting the flow path, this design minimizes the pressure surface area exerted on the ball core, which substantially lowers operational torque and optimizes sealing performance in high-pressure hydraulic or steam applications. Because they contain less raw material, reduced bore configurations are approximately 30% lighter and structurally more compact than full-bore equivalents, making them a highly cost-effective and space-saving solution for systems where slight flow restriction is permissible. Project engineers can achieve maximum fiscal efficiency and downsize piping strain by sourcing high-performance reduced bore ball valves directly from certified manufacturers in China via our specialized B2B commercial platform.
