Valves, Pumps, Turbomachinery and Compressors
An introduction to valves standards
Valves are essential components across industries such as oil and gas, power generation, water treatment and chemical processing. They regulate and/or isolate fluid flow, ensuring safe and efficient system operation. To guarantee reliability and performance, valves must conform to rigorous standards developed by organizations like the American Petroleum Institute (API), the American Society of Mechanical Engineers (ASME), the Manufacturers Standardization Society (MSS) and the International Organization for Standardization (ISO).
