Full Port Gate Valve

A full port gate valve (also known as a full-bore gate valve) is a multi-turn, linear-motion shut-off valve designed with an internal flow passage and seat opening that exactly match the inside diameter of the connecting pipeline. Unlike standard or reduced port gate valves—which feature a restricted flow path one size smaller than the pipe diameter—the full port design creates a straight, completely unobstructed tunnel when the wedge is fully raised, resulting in virtually zero fluid resistance, minimal turbulence, and negligible pressure drop. Conforming to standard specifications such as API 600, ASME B16.34, and API 6D, these high-capacity, heavy-duty valves are primary selections in crude oil transmission lines, abrasive mining slurry networks, and high-flow process headers, allowing piping engineers and pipeline operators to secure restriction-free flow and reliable long-term service by importing certified full port gate valves directly from leading manufacturers in China via our advanced B2B commercial platform.
