JIS B2073 Gate Valve

A JIS B2073 gate valve is a multi-turn linear isolation valve cast or forged from steel, manufactured and certified in accordance with Japanese Industrial Standard JIS B2073 (governing medium-pressure flanged steel gate valves). Operating via a rising or non-rising stem driving a wedge perpendicular to flow, it provides a full-bore, cavity-free passage with minimal flow resistance when open and dependable, zero-leakage shut-off when closed. Conforming to Japanese manufacturing codes and JIS B2220 flange dimensions, these standardized valves are critical specifications in Japanese shipbuilding yards, chemical processing plants, and district energy utilities, allowing system operators and maintenance engineers to maintain standardized piping loops by importing certified JIS B2073 gate valves directly from leading manufacturers in China via our advanced B2B commercial platform.
