Brahma Gas valve EG15*S*GMO 13924360

The Brahma EG15*S*GMO gas valve (SKU 13924360) is a solenoid-operated shut-off and regulating valve for civil and industrial gas applications. It operates on AC or DC supply (220 V, 50–60 Hz) with a power consumption of 22 W, and features a normally closed design with a closing time of 1 second. The valve includes a mesh filter at the inlet (1 mm cell size), a hydraulic shock absorber for controlled opening, and supports both fast and slow opening modes. It is certified to CE (registration 63AQ0626) under directives 90/396 and 93/68, with a maximum operating pressure of 500 mbar and a flow capacity of 8 m³/h. The body is die-cast aluminum, weighs 850 g, and has a DN15 connection with terminal block wiring and IP40 protection.

When selecting a replacement gas valve of this type, verify the supply voltage (AC or DC), frequency, and power consumption to match the control system. Check the maximum operating pressure (500 mbar) and the nominal diameter (DN15) against the existing piping. Ensure the valve's opening and closing times (1 s) and flow capacity (8 m³/h) meet the burner requirements. The valve can be installed vertically or horizontally, and the arrow on the body must align with gas flow direction. Use a hex wrench for mounting to avoid twisting the casing, and confirm the electrical connection type (terminal block) and protection rating (IP40) are compatible.

Common failures of solenoid gas valves include coil burnout, leading to the valve not opening or closing properly, which may cause the burner to fail to ignite or shut down unexpectedly. Debris clogging the inlet mesh filter can restrict gas flow, resulting in reduced burner output or flame instability. A faulty hydraulic shock absorber may cause erratic opening or excessive noise during operation. Check the coil resistance and supply voltage, inspect the filter for blockages, and verify the valve opens and closes fully when powered.
