Excess flow valves - Part 2: Excess flow valves for service lines
Abstract
This document is prepared by the working committee NA 032-03-02 AA "Components and auxiliary materials - gas" in the Gas Technology Standards Committee (NAGas) of DIN Deutsches Institut für Normung e. V. in agreement with the German Technical and Scientific Association for Gas and Water (DVGW). This document is to be included in the "Gas" rules and regulations of the DVGW, German Technical and Scientific Association for Gas and Water. This document specifies requirements and tests of excess flow valves for the operating pressure range from 25 hPa to 0.5 MPa according to Table 1 up to a nominal diameter of DN 50 with defined flow direction (hereinafter referred to with the abbreviation "GS"), which are used in contact with gases classified according to DVGW Code of Practice G 260 (but not for liquefied gas in the liquid phase). This includes hydrogen-blends and hydrogen.
