Types of valve standards – API, ANSI, MSS, BSI, IOS

Types of valve standards

Listing of the basic specifications used in the design and manufacture of valves and fittings follows different valve standards like American Petroleum Institute (API) Standards, American Society of Mechanical Engineers (ASME), MSS, NACE, BSI, IOS etc.
