Choosing and fitting
When choosing a replacement for this type of gas solenoid valve, confirm that the nominal diameter and connection thread match the existing pipeline. Threaded versions are available for pipes from DN10 to DN65, and flanged versions for DN40 and DN50. Check the supply voltage and frequency, as well as the maximum inlet pressure, to ensure the valve suits the installation. Also note whether auxiliary connections (screw plugs) are needed on either side.
