What are the differences between low-pressure valves and high-pressure valves?

The key differences between low-pressure valves and high-pressure valves are as follows:  

1. Pressure and flow rate:  

- **Low-pressure valves**: Pressure ≤ 1.6 MPa, flow rate <0.6 cubic meters per hour. These valves are suitable for low-flow applications such as household gas stoves and water heaters.  

- **High-pressure valves**: Pressure ≥ 6.4 MPa, with a high flow rate and adjustable heat output. They are specifically designed for high-power commercial cooking appliances.  

2. Applications and usage scenarios:  

- **Low-pressure valves**: Used in household gas equipment, they offer high safety and a lower risk of gas leaks.  

- **High-pressure valves**: Commonly used in commercial settings such as hotels and canteens, where regular inspections of their sealing integrity are required.  

3. Safety considerations:  

- In the event of a malfunction, high-pressure valves allow gas to leak rapidly, posing a higher risk of explosion. Low-pressure valves, on the other hand, have a slower gas leak rate and pose a lower risk. It is strictly prohibited to use high-pressure valves in household gas stoves.  

4. Appearance and structure:  

- **High-pressure valves** typically have adjustable knobs and a more complex structure.  

- **Low-pressure valves** have a simpler structure and a narrower range of adjustment.
