A valve designed and manufactured according to DIN (Deutsches Institut für Normung) standards complies with the industrial product standards set in Germany and the European Union. These standards define critical parameters such as dimensions, pressure ratings, materials, and manufacturing processes, specifically for valves, flanges, and other connection components used in piping systems.
A valve that meets DIN standards signifies the following:
Connection Type and Dimensions: The valve adheres to the flange connection dimensions and specifications as outlined in DIN standards, ensuring proper fitting and compatibility with European or DIN-based piping systems.
Pressure Rating: DIN valves are manufactured to withstand specific pressure levels, denoted by pressure classes such as PN10, PN16, or PN25, indicating the valve's ability to handle various pressure ranges according to DIN standards.
Material and Manufacturing Quality: The materials used in DIN valves and their manufacturing processes must comply with DIN’s stringent quality requirements. This ensures durability, reliability, and safety in industrial applications.
Application Areas: DIN valves are widely used in European markets and other regions where DIN standards are preferred. These valves are commonly applied in industries such as oil and gas, chemical processing, and power generation, where compatibility with DIN piping systems is essential.
