Picture of gas self-closing valve

Natural gas self-closing valve will prevent gas output under abnormal conditions, and it will automatically close the valve when the gas in the pipe network stops or the pressure is too high.

Pipeline gas self-closing valve, referred to as self-closing valve, is a device installed on the pipeline of low-pressure gas system. When the gas supply pressure of the pipeline is under-pressure or over-pressure, it can be automatically closed and manually opened without electricity or other external power.

The self-closing valve installed at the joint between the end of the pipeline and the rubber hose behind the gas meter should have the function of pressure loss and closing. The pipeline gas self-closing valve is suitable for pipeline natural gas, liquefied petroleum gas and artificial gas.

State description of natural gas self-closing valve

1. Under normal conditions, the self-closing valve reset button pull rod will be in the green line calibration state.

2. When the red line on the pull rod of the reset button pops up, it means that the pressure in the gas pipeline is too high and the self-closing valve will automatically close.

3. When the reset button and the pull rod are fully retracted, it means that the pipe network stops gas or the gas hose falls off, and the self-closing valve will automatically close.
