DIN Standards Reference Table
The following table organizes common DIN valve standards by category for quick reference. This is a representative sample; the original source contains a more extensive list.
Key Terms & Specifications
Based on the extracted standard titles, several key engineering terms and specifications are frequently referenced:
- PN (Pressure Nominal): A designator for pressure rating (e.g., PN 10, PN 40). Represents the maximum allowable pressure in bar at a reference temperature (typically for water at 20°C).
- DN (Nominal Diameter): A dimensionless number used to define the nominal size of piping system components (e.g., DN 250).
- Test Pressure: The pressure to which a valve or component is subjected during a verification test, often higher than the working pressure (e.g., up to 300 bar, 450 bar).
- Face-to-Face Dimension: A critical valve measurement defined by standards (like DIN 3202) that ensures interchangeability between valves from different manufacturers.
- Common Valve Types Defined: The standards explicitly categorize and define requirements for Gate Valves, Globe Valves, Ball Valves, Check Valves, Safety Valves, and Diaphragm Valves.
- Material Designations: Standards frequently reference specific material families:
- Cast Iron (e.g., DIN 3352-2)
- Steel (e.g., DIN 3356-3 Unalloyed steel, DIN 3356-4 High temperature steel)
- Stainless Steel (e.g., DIN 3356-5)
- Nonferrous Metals (e.g., DIN 3357-4)
- Plastics (e.g., DIN 3441 for PVC-U, DIN 3442 for PP)
- Elastomeric Seats (e.g., DIN 3352-4)
