A reduced bore gate valve (or reduced port gate valve) is a linear-motion isolation valve where the internal flow path through the valve body is smaller than the nominal pipe size of the connecting pipeline. This geometric restriction slightly increases fluid velocity and introduces a minor pressure drop across the line, but it allows for a noticeably smaller, lighter, and more economical valve body structure compared to full-bore designs. Its internal wedge moves perpendicular to the flow to achieve a tight, bidirectional metal-to-metal shutoff. Reduced bore gate valves are widely specified for small-bore piping systems, high-pressure utility manifolds, and industrial processing lines where full pigging capabilities are not required and space optimization is essential. Piping layout designers and sourcing networks can minimize overall system weight and reduce structural installation footprints by importing premium reduced bore gate valves directly from certified manufacturers in China via our advanced B2B platform.
