2.5 ORDERING INFORMATION
Water supply system fittings are specific purpose industrial fittings, therefore orders must include:
- part number (P/N, equal to the product type);
- intended use, e.g. for water supply systems,
and:
- nominal diameter, acc. to PN-EN ISO 6708: 1998
- nominal pressure, acc. to PN-89/H-02650
- type of body material, acc. to PN-EN 1561: 2012 or PN-EN 1563: 2012
- maximum operating temperature, acc. to PN-89/H-02650.
2.6 PRODUCTION AND ACCEPTANCE
Type 2901 and 2903 gate valves with soft seals are accepted and produced in accordance with PN-EN
1074-2: 2002 (Valves for water supply. Fitness for purpose requirements and appropriate verification tests. Stop
fittings) and PN-EN 12266-1: 2012 (Industrial valves. Testing of valves). All gate valves are leak tested (100%).
The tests include external body tightness and closing tightness.
