What does it mean when the gas meter shows 'valve closed'?

[OPiper]

The gas meter displaying 'valve closed' indicates that there may be no balance due to unpaid fees, insufficient pressure, or low battery in the electronic gas meter. Reasons why the gas meter shows 'valve closed' despite having a balance: 1. Insufficient pressure. The gas meter must close the valve when the pressure is low to prevent accidents. This issue requires contacting the gas supplier for resolution, as only they can control the gas supply pressure or repair the pipeline. 2. Low battery in the electronic gas meter. The electronic gas meter has an internal electrically controlled valve that operates based on detected pressure. When the pressure is insufficient, the valve automatically closes. However, when the battery is low, the detection probe malfunctions, and the pressure signal becomes weak. The LCD panel consumes very little power, so it may still display normal readings and show 'low pressure.' When the battery level drops further, it will display 'valve closed.' The solution is to replace the battery and reinsert the gas card to reopen the internal solenoid valve of the gas meter; otherwise, there will still be no gas supply.
