What is the ISO valve standard?

ISO valve standards are valve technical specifications developed by the International Organization for Sanderdizaion (ISO), which aim to provide unified global technical requirements for the design, manufacture, testing and use of industrial valves around the world. Unlike API standards that focus on the oil and gas industry, ISO standards focus more on cross-industry applicability and international compatibility. They are widely used in multiple industries such as petroleum, chemicals, electricity, water treatment, and pharmaceuticals. They are widely adopted in markets such as Europe, Asia, and Africa, and are particularly dominant in Europe, Asia, and emerging markets.

Background and core objectives of ISO valve standards
