Brahma Double gas solenoid valve 13991920

The Brahma 13991920 is a double gas solenoid valve with two normally-closed solenoid valves, designed for automatic gas supply control in burners. It operates at line pressures up to 500 mbar and has a nominal diameter of 15 mm with Rp 1/2 connection thread. The valve is certified to EN161 class A group 2, has a closing time of 1 second, and is powered by 230 V AC. It features an aluminum casting housing with IP40 protection and operates in ambient temperatures from -10 to 60 °C. The valve is suitable for horizontal and vertical installation and connects via a four-pin plug.

When selecting a replacement double gas solenoid valve, ensure the nominal diameter, connection thread, and maximum inlet pressure match the system requirements. Verify the supply voltage and electrical connection type (e.g., plug configuration) are compatible with the control unit. The valve must be certified to the appropriate standard (e.g., EN161) and have the correct gas group classification. Installation can be in horizontal or vertical positions, but check the manufacturer's guidelines for orientation-specific requirements.

Common failures of double gas solenoid valves include sticking due to debris or wear, leading to incomplete closure or failure to open. This may cause burner ignition issues, gas flow irregularities, or safety lockouts. Electrical faults, such as coil burnout or wiring issues, can result in no valve operation. Check for proper voltage supply, clean the valve internals, and inspect seals for damage.
