GEMÜ 550 angle seat globe valve
The GEMÜ 550 angle seat globe valve from the Ingelfingen-based valve specialist GEMÜ is now available with gas approval in accordance with DVGW (German Technical and Scientific Association for Gas and Water).
The GEMÜ 550 angle seat globe valve has been certified by the DVGW (German Technical and Scientific Association for Gas and Water) to DIN EN 161:2013-04 and DIN EN 16678:2016-02 standards. Therefore, the angle seat globe valve can be used as a shut-off valve for combustible gases in the gas families 2 and 3 in gas burners and gas appliances. Typical gases in this family include natural gases, petroleum gases and biogases, consisting mainly of methane, liquid gases containing propane and butane, and hydrogen.
The designs of the GEMÜ 550 angle seat globe valve that are suitable for use with combustible gases are those with the flow direction “over the seat”. This does not result in the sealing force being reduced by the inlet pressure. The maximum operating pressure is 10 bar.
