Deep Technology Analysis
| Module | Parameter Details | Design Significance |
| Main Structure | High-purity brass forging, precision machining | This fundamentally ensures the strength, pressure resistance and extremely long service life of the valve body in humid and corrosive environments, far exceeding that of ordinary alloy materials. |
| Operating method | Rocker swing-type handle | Just press the palm to quickly open or close. No need to rotate. Even when wearing gloves or in low-visibility environments, it can be operated blindly. The response speed has increased by more than 50%. |
| Safety Core | Integrated adjustable safety valve | When the system pressure abnormally rises, it automatically releases the pressure, serving as a crucial safety barrier to prevent gas cylinder overfilling and accidental explosion. This ensures that your purchasing decisions are worry-free. |
| Interface Specification | Entrance: PZ19.2 Exit: W21.8 Thread of immersion tube: M10x1 |
It fully complies with the mainstream interface standards of fire extinguisher cylinder valves, ensuring perfect compatibility with various models of fire extinguishers from both domestic and international markets. There is no worry about replacement or upgrade. |
| Pressure performance - Working pressure | 180-250 bar | The broad and high-standard range of working pressure fully meets the filling and usage requirements of various fire extinguishing agents such as dry powder and carbon dioxide, with ample performance redundancy. |
| Adaptation Instructions | Pressure gauge connection thread: None | The structure is more concise, with fewer failure points. Pressure detection is usually accomplished through filling equipment or independent instruments, which is in line with most operation procedures. |

FAQ
Q: What is the function of the safety valve on the valve? Do we need to adjust it ourselves?
A: This safety valve is the core protective device. Its main function is to automatically open and release pressure when the fire extinguisher encounters abnormal high temperatures (such as in a fire scene) or when the pressure exceeds the set value (usually 1.2-1.5 times the working pressure) due to incorrect filling, to prevent the cylinder from exploding. The valve has been calibrated according to standards before leaving the factory. Users are strictly prohibited from adjusting it themselves to avoid potential safety hazards. Under normal use and when filling at the specified pressure, it remains in a closed state.
Q: Why is there no pressure gauge interface? How can we detect the pressure?
A: This is a manifestation of professional design. Valves without a gauge head are simpler, more reliable, and have lower costs, and are suitable for use in production process integration or maintenance filling stations. In these scenarios, pressure detection is usually completed on an independent filling equipment line or through the operation of a dedicated filling connector with a gauge head. This avoids integrating easily damaged pressure gauges on each valve and reduces the overall failure rate.
Q: Is brass material durable in coastal or corrosive environments?
A: High-quality brass has excellent resistance to atmospheric and freshwater corrosion. For coastal areas with high salt spray or highly corrosive industrial environments, we recommend additional routine maintenance. If you have special requirements for extreme environments, you can contact us to inquire about custom options such as nickel plating or other surface treatments.
