ISO 5752 Butterfly Valve

An ISO 5752 butterfly valve is a quarter-turn rotary valve designed and manufactured in strict compliance with the international standard ISO 5752, which establishes standardized face-to-face and end-to-center dimensions for metal valves used in flanged pipe systems. This rigorous dimensional standardization ensures total interchangeability with other conforming valves worldwide, facilitating seamless retrofitting and system upgrades without requiring modifications to existing pipe hangers or flange spacings. These universally compatible valves are critical specifications in international marine construction, global oil and gas infrastructure, and municipal water supply grids, allowing procurement managers and piping designers to simplify global logistics and replacement schedules by importing certified ISO 5752 butterfly valves directly from leading manufacturers in China via our advanced B2B commercial platform.
