Brahma Gas valve EG30*S.2*GMO 13940500

The Brahma EG30*S.2*GMO gas valve (SKU 13940500) is a normally closed type valve designed for civil and industrial use. It operates with a supply voltage of 230 V at 50–60 Hz and can be powered by alternating or direct current, featuring an internal rectification circuit for silent operation. The valve has a nominal diameter of 30 mm, a working pressure range of 0–350 mbar, and a closing time of 1 second. It is certified to EN 161, class A, group 2, and complies with European directives 90/396 and 93/68. The body is made of die-cast aluminum, with an IP54 protection class and a PG9 cable gland.

When selecting a gas valve of this type, ensure the nominal diameter, supply voltage, and working pressure range match the system requirements. The valve can be installed vertically or horizontally, and the arrow on the body must align with the fuel flow direction. Use a hex key to secure the valve without twisting the shell, and prevent foreign objects from entering the body. Verify that the maximum inlet pressure does not exceed the value indicated on the valve label.

Common failures in gas valves of this kind include sticking due to debris or contamination, leading to slow or incomplete opening or closing. Electrical issues such as coil burnout or rectifier failure can cause the valve to remain closed or open intermittently. Symptoms on the equipment include burner ignition failure, unstable flame, or gas flow continuing after shutdown. Check for proper voltage supply, clean the valve internals, and inspect the coil and rectifier for damage.
