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:
