JIS Butterfly Valve

A JIS butterfly valve is a highly efficient quarter-turn rotary fluid control valve engineered, wall-dimensioned, and pressure-tested to comply with Japanese Industrial Standards (JIS), such as JIS B2032 or JIS B2002. This design ensures that the valve's wafer or lug body face-to-face dimensions, stem connections, and flange bolt-hole configurations match regional piping specifications perfectly, typically rated under JIS 5K, 10K, or 16K designations. It utilizes a central disc that rotates 90 degrees within an elastomeric or metallic seat ring to provide rapid, low-torque isolation and macro-throttling control while maintaining a very slim physical footprint that lowers pipeline material costs. Marine engineering networks and Asia-Pacific infrastructure contractors can ensure total regional compliance and secure compact fluid control by sourcing certified JIS butterfly valves directly from premier manufacturers in China via our advanced B2B digital marketplace.
