What is the purpose of a gas safety shut-off valve?

Gas pipeline self-closing valve is a kind of safety valve, which is the preferred passive safety emergency cut-off device for indoor gas pipelines. It is generally installed in front of stoves or water heaters.

self-closing valve installation location

The physical principle of the self-closing valve is based on the permanent magnet placed inside the valve as the data carrier, driven by the directional magnetic force and the gas pressure in the pipeline, relying on the micro-pressure difference sensor and the multi-pole linkage permanent magnet mechanism to control the gas pressure passing through it. The flow parameter is sensed and identified, and it will automatically shut down when it exceeds the safe setting value.

It has the functions of overpressure self-closing, undervoltage self-closing, and overcurrent self-closing. When the pressure in the gas pipeline is lower or higher than the set value, or when the gas flow rate is higher than the set value, the valve will be automatically closed in time to prevent gas leakage, thereby avoiding gas explosion accidents; after the valve is closed, it cannot be opened automatically, you need to manually open it after confirming the safety.

Features and advantages of pipeline self-closing safety valve:

1. Reliable sealing

2. High sensitivity

3. Quick response

4. Small size

5. No energy consumption

6. Easy to install and use

7. Long service life, 10 years
