the hose is disconnected within 2 meters and automatically closed within 2 seconds
After the valve is closed, the inlet pressure ≥6KPa must not be started by itself.
Working environment temperature
-10°C ~ 40°C
Features: - Solid construction, simple installation, easy to use - Gas pipeline self-closing valve to help solve your safety worries in using natural gas - Stable performance, convenient to use, no electricity or any external power, automatic shutdown - With under pressure, over pressure, loss of pressure automatic closing and manual reset function - When the gas is stopped, the gas supply is abnormal or the hose is detached, etc., it is automatically closed to prevent leakage.
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
