Brahma Gas valve EG12*SR*GMO 13912001

The Brahma EG12*SR*GMO gas valve (SKU 13912001) is a normally closed solenoid valve designed for gas burners and boilers. It operates on 230 V AC (50–60 Hz) with a power consumption of 20 W, and features a built-in rectifier bridge for DC coil operation. The valve has a nominal diameter of 15 mm, a maximum inlet pressure of 500 mbar, and a flow capacity of 7.5 m³/h. It is certified to EN 161 (CE registration number 63AQ0626) and complies with directives 90/396 and 93/68. The die-cast aluminum body allows vertical or horizontal installation, and the valve includes a mesh filter at the inlet (1 mm cell size) and a hydraulic shock absorber for controlled opening.

When selecting a replacement gas valve of this type, verify the nominal diameter, maximum inlet pressure, supply voltage, and frequency match the system requirements. Ensure the valve's flow capacity is adequate for the burner's demand. Installation must align the arrow on the body with the direction of gas flow, and avoid twisting the shell during mounting—use a hex wrench on the valve body. The valve can be installed vertically or horizontally, and the electrical connection is via a terminal block with IP40 protection.

Common failures in gas valves of this kind include coil burnout, which prevents the valve from opening, or debris clogging the inlet filter, causing reduced gas flow. A stuck valve may result in no gas supply or continuous flow, leading to burner ignition failure or unsafe operation. Check the coil resistance and supply voltage, inspect the filter for blockages, and verify the valve opens and closes within the specified times (1 second).
