Brahma Gas valve EG30*S.2*GFD 13942702

The Brahma Gas valve EG30*S. 2*GFD 13942702 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 valve shuts off and meters the gas supply to the burner, opening on command from the burner control only when the gas pressure switch confirms safe supply pressure. In premix burners, a pneumatic gas/air link connects the valve to the fan, modulating gas flow in proportion to combustion air.

Parts of this type are selected by brand and series, connection size, coil voltage (typically 230 V or 24 V AC/DC), and function - single or double solenoid, slow opening, servo-regulated, or as a multiblock that integrates a filter and regulator. For this particular article, the engineer must verify the connection size (Rp 1/2" to 2" or flanged) and coil voltage from the existing installation or system documentation. When replacing a valve of this type, confirm that the replacement matches both the electrical supply and the mechanical connection; if the original was a multiblock, ensure the new unit includes or can accept the same auxiliary components.

Common failure modes are coil burnout, leaking valve seat, drifting outlet pressure, and a seized servo regulator. The coil itself is often replaceable separately from the valve body. In the ignition sequence, the gas valve is energised by the burner control after pre-purge and the establishment of the ignition spark; the valve admits gas and a flame must be proved within the safety time. If the valve fails, the burner may not ignite, or may shut down during operation due to loss of flame or pressure irregularities.
