Why can't the natural gas valve be opened after being closed?

[LaNora]

Low gas pressure causes the valve to close automatically. Some households may use manual valves, where you can simply turn the main valve. For automatic valves, you need to locate the battery compartment, remove the batteries inside, wait for about ten minutes, and then reinsert the batteries. The valve will automatically open, allowing you to use the gas. If this does not resolve the issue, you can call the gas service hotline. Additionally, there is a red plastic button on the top of the natural gas meter, which is an automatic emergency shut-off valve. If the gas consumption exceeds a certain limit, it will assume a gas leak and close automatically. To open it, simply lift the transparent plastic cover above the button and gently pull the red button upward.
