Product Features

Automatic shutdown due to over-current

When the gas flow exceeds the normal specified value, the valve will automatically close to prevent gas leakage accidents caused by gas pipe falling off or rupture.

Automatic shutdown due to under-pressure

When the gas supply pressure is insufficient due to insufficient gas source, peak gas usage period, ice blockage, gas outage, etc., the gas supply will be automatically cut off to prevent the stove from being turned off due to low-pressure gas supply and avoid leakage accidents;

Automatic shutdown due to over-pressure

When the gas pressure regulating equipment in the community fails, the gas pressure in the user's pipeline exceeds the safe use range, and the gas supply will be automatically cut off to prevent the gas hose from falling off or ruptured due to high pressure, or the stove from being damaged, to avoid leakage accidents.

Product Advantages
