2.5 ORDERING INFORMATION
Water supply system valves are specific purpose industrial valves, therefore
purchase orders must include:
- Part Number (P/N)
- 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 1563: 2012
- maximum operating temperature, acc. to PN-89/H-02650.
2.6 PRODUCTION AND ACCEPTANCE
The Type BA P/N 1350 antipollution valves are manufactured and accepted in accordance with:
PN-EN 1074-3:2002 (Valves for water supply. Fitness for purpose requirements and appropriate verification
tests. Check valves) and PN-EN 12266-1:2007 (Industrial valves. Testing of metallic valves). All valves are leak
tested (100%). The tests include external body tightness and closing tightness at high and low pressure values.
