Brahma Gas solenoid valve 13924760

The Brahma Gas solenoid valve 13924760 is a normally closed gas valve designed for use in gas control systems. It operates with a supply voltage of 220–240 V at 50–60 Hz, consuming 22 W of power. The valve has a nominal diameter of 15 mm, a maximum inlet pressure of 500 mbar, and a flow capacity of 8 m³/h. It features a built-in rectifier bridge for DC operation, a mesh filter at the inlet with a 1 mm cell size, and a flow regulator for slow and silent opening. The valve body is made of die-cast aluminum, and it is classified as class A, gas group 2, with a closing time of 1 second.

When selecting a replacement gas valve of this type, ensure that the nominal diameter, maximum inlet pressure, supply voltage, and frequency match the system requirements. The valve can be installed in both vertical and horizontal positions, and the flow direction must align with the arrow marked on the housing. The electrical connection is made to a terminal block with IP40 protection, and the cable gland size is PG9. Before installation, verify that the pipeline is free of foreign objects and that the maximum inlet pressure does not exceed the valve's rating.

Common failures of gas solenoid valves include coil burnout, which may cause the valve to fail to open or close, leading to no gas flow or continuous flow. A clogged inlet filter can restrict gas flow, resulting in reduced burner output. Leaks may occur due to worn seals or improper installation, causing gas odor or pressure drops. If the valve operates slowly or noisily, it may indicate a faulty rectifier or flow regulator. Check the electrical connections, filter condition, and valve operation for proper function.
