GAS NONRETURN VALVES IN ACCORDANCE WITH EN 7302 The safety devices are used to safeguard plants, pipeline systems and tapping points. The check valves type GRV prevent gas return. The flashbackresistant gas nonreturn valves type GRS prevent gas return as well as flashback if compressed air is used as an oidant. THE GAS NONRETURN VALVES ARE AVAILABLE IN THREE SIZES, DN, DN 32 AND DN 0, WITH THREAD FROM ½ TO 2 AS WELL AS SPECIAL FLANGE CONNECTION UP TO NOMINAL DIAMETER OF DN 0. CERTIFIED SAFETY YOU CAN RELY ON! The safety devices satisfy the requirements specified in all relevant standards and directives. They are tested by BAM in Berlin and are registered under the DVGW certification mark: NG4390CQ0062 (gas nonreturn valves/check valves, Model GRV) and DG4390CQ006 (gas nonreturn valves (flashbackresistant), Model GRS) TECHNICAL DATA Gas nonreturn valves / Check valves Gas nonreturn valves (flashback resistant) Types GRV ½" GRV ¾" GRV " GRV 32 " GRV 32 ¼" GRV 0 ½" GRV 0 2" GRV 0 FLANGE DN 0 GRS ½" GRS ¾" GRS " GRS 32 " GRS 32 ¼" GRS 0 ½" GRS 0 2" GRV 0 FLANGE DN 0 Safety elements DF (dust filter) NV (gas nonreturn valve) FD (flame deflector) Maimum working pressure (bar) bar = 0, MPa Town gas, grid gas (C),,,,, Hydrogen (H),,,,, Natural gas (M) Propan (P) Cleaned Biogas Oygen (O) Nitrogen (N) Inert gases (N) Compressed air (D) Inlet pressure (mbar) Flow rate (Nm/h³)* 22 24 30 3 9 00 00 9 2 23 29 33 90 9 9 40 33 36 40 0 0 3 34 38 2 43 47 47 60 40 44 6 70 9 0 0 38 42 46 62 67 8 90 90 80 0 2 7 80 20 2 2 46 49 7 76 0 9 9 00 8 6 80 8 240 0 0 2 62 76 8 228 238 238 00 3 4 0 20 00 0 0 24 38 47 90 0 47 *All flow rates are measured with air 3
