Brahma Gas valve 13871501

The Brahma Gas valve 13871501, model EG12*A*AFD, is a gas valve designed for precise control of gas burner valves. It provides opening and closing of valves when voltage is applied, with high heat resistance and durable insulation. The design is resistant to vibration. This component is a safety and metering device that interrupts or admits gas to the burner in response to signals from the burner control. The valve opens only when the burner control commands it and after the gas pressure switch confirms that the gas supply is within the permitted pressure range.

Parts of this type are selected by brand and series, connection size (commonly Rp 1/2" to 2" or flanged), coil voltage (230 V or 24 V AC/DC), and the specific function required - single or double solenoid, slow opening, servo-regulated, or a multiblock that also contains a filter and regulator. In premix burners, a pneumatic gas/air link often ties the valve to the fan, so the valve's response to air pressure may be relevant. When replacing a gas valve, always check the coil voltage and the mechanical connections match the existing installation; the valve body and the coil may be sourced independently if only one part has failed.

Common issues include coil burnout (the coil is often available separately), a leaking seat that causes gas to pass when closed, drifting outlet pressure due to wear in the regulator, or a seized servo regulator. These failures can result in the burner not igniting, irregular flame, or gas leakage when the valve is supposed to be closed.
