Instructions:
1. Opening mode under normal air pressure:
Close the cooker or the ball valve at the back end of the self-closing valve. Manually pull up the handle and hold it for 3-5 seconds. After releasing, the valve will remain open automatically

2. Overpressure emergency treatment plan:
When the blue handle of the valve is disengaged, the valve is in overpressure condition. The rear end ball valve should be closed immediately to contact the gas company to handle the fault. After the fault is removed, open the ball valve to return the valve to the closed position, and then follow the first step to open the valve

3. Undervoltage treatment plan:
When the self-closing valve is automatically in the closed position, please check whether the hose between the valve and the cooker is off or burst. If there is no such phenomenon, check if the intake pressure is lower than the normal working pressure. Open the valve after troubleshooting and normal ventilation
