Brahma Gas solenoid valves EG12*S*CFD 13900832

Brahma EG12*S*CFD gas solenoid valve, SKU 13900832, is a normally closed valve suitable for civil and industrial applications. It operates on alternating or direct current with a 230 V supply voltage and 50–60 Hz frequency, consuming 20 W. 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 features a mesh filter at the inlet with a 1 mm cell size, a die-cast aluminum body, and a PG9 cable gland. The valve is certified to EN161 with CE marking (registration 63AQ0626) and complies with directives 90/396 and 93/68. It offers fast, silent opening and can be installed vertically or horizontally.

When selecting a replacement solenoid gas valve of this type, ensure the nominal diameter, inlet pressure rating, supply voltage, and frequency match the system requirements. The valve must be compatible with the gas group and comply with relevant standards. Installation should follow the arrow on the body indicating flow direction, and the valve can be mounted in vertical or horizontal positions. Use a hex wrench to avoid twisting the shell during mounting, and ensure no foreign objects enter the valve body.

Common failures of solenoid gas valves include coil burnout, which may cause the valve to fail open or closed, leading to gas flow issues. A stuck valve can result in no gas supply or continuous flow, causing burner ignition problems or unsafe operation. Check the coil resistance and ensure the valve opens and closes properly with power applied. Inspect the mesh filter for clogging, which can restrict flow and affect performance.
