A gas automatic shut-off valve with built-in valve and pressure measurement hole is a safety device installed on indoor low-pressure gas pipelines. The working principle of a Gas automatic shut-off valve is based on the combination of a magnetic linkage mechanism and a pressure sensing mechanism. The Gas automatic shut-off valve has threaded connection, male/male, and the specification is 1/2'', which is easy to install.

The gas automatic shut-off valve with built-in valve and pressure measurement hole automatically cuts off the gas supply in abnormal situations such as overpressure, underpressure, or hose detachment by real-time monitoring of gas pressure changes in the pipeline. The core principle is to use the magnetic properties of permanent magnet materials in conjunction with spring reset force to achieve automatic closure, with manual opening required for restart. With pressure measurement hole can install a continuously device to monitor the gas pressure in the pipeline. Users can directly read the pressure value through connected devices such as pressure gauges or sensors, enabling timely detection of pressure fluctuations or abnormalities. By combining the valve and pressure measurement device into a single body, the design reduces the number of components and assembly steps, resulting in a more compact structure. This not only saves installation space but also minimizes connection points, lowering the risk of leaks and improving overall sealing and safety.
