In fact, there is no distinction between commercial and domestic LPG pressure reducing valves (they are all residential products differentiated from industrial ones). It is only that there are different specifications for the amount of gas allowed to pass through a pressure reducing valve during normal operation, and for domestic use a smaller gas volume is usually chosen.

Liquefied petroleum gas pressure-reducing valves, the liquefied petroleum gas flow allowed to pass through the size of different specifications.

When the volume of gas used and the specifications of the pressure reducing valve match, the pressure reducing valve works best;

When an accident occurs such as a gas pipe falling off, the larger the specifications of the pressure reducing valve, the greater the volume of gas leaked out;

The pressure reducing valve is allowed to have a tiny leakage of liquefied petroleum gas, the larger the specifications of the allowable leakage is also the greater.

So families usually use small size pressure reducing valves.

The sizes of pressure-reducing valves by hourly flow rate are: 0.6 cubic meters (for stove alone), 1.2 cubic meters (for stove + water heater), 2.5 cubic meters (for heating boiler), and larger sizes. General family selection of 1.2 cubic meters will be completely sufficient, open restaurant only need 2.5 or larger pressure reducing valve.
