Resumen:
This standard applies to requirements and tests of excess flow valves (hereinafter referred to as "GS") up to a nominal diameter of DN 50 with a defined flow direction. They are operated with gases in accordance with DVGW Code of Practice G 260 (but not for LPG in the liquid phase) and apply to the operating pressure ranges from 15 mbar to 100 mbar. The standard is based on the DVGW provisional test specification VP 305-1:2007-12 "Excessflow valves for gas installation". It regulates the requirements and tests on GS of types M (15 mbar to 100 mbar) and K (15 mbar to 100 mbar) in accordance with the requirements of DVGW Code of Practice G 600 "Technical Rules for Gas Installations - TRGI 2008".
