It is designed for systems with a maximum inlet pressure of 100 mbar. The valve operates within an ambient temperature range of -10 to 60 °C and has a maximum excess pressure of 360 mbar. It features an integrated relay for minimum gas pressure control, a protective filter, two pressure measurement nipples, and a set of gaskets with various configurations. The valve has an ingress protection rating of IP 54 and a net weight of 4.3 kg. It requires a supply voltage of 230 V.

When selecting a replacement gas valve of this type, ensure the maximum inlet pressure, supply voltage, and ambient temperature range match the system requirements. Verify the valve's dimensions and connection size against the existing installation. The valve should be installed in accordance with the manufacturer's instructions, ensuring proper orientation and secure mounting. Check that the protective filter and gaskets are compatible with the specific gas type and system configuration.

Common failure modes for gas valves of this kind include sticking or leaking due to debris or wear, which can cause inconsistent gas flow or failure to shut off. Symptoms may include burner ignition failure, unstable flame, or gas odor. Check the valve for proper operation by testing the integrated relay and pressure measurement nipples. Inspect the protective filter for clogging and replace gaskets if they show signs of deterioration.
