(Anke Fire) are able to provide good quality products, The 1-2KG extinguisher copper valve 1135 is made of high-quality brass, which has excellent corrosion resistance, wear resistance and oxidation resistance, and can maintain its physical properties for a long time in various harsh environments.
The strength and ductility of brass make it suitable for the management of high-pressure gas, ensuring that the fire extinguisher can still work safely and stably under extreme conditions. The valve is designed for 1-2 kg fire extinguishers and can withstand high internal gas pressure while ensuring that the gas can be released within a safe range.
The 1-2KG extinguisher copper valve 1135 has a built-in safety pressure relief device. When the internal pressure is too high, the safety valve will automatically release excess pressure to prevent the gas cylinder from bursting or other dangerous situations. This design greatly improves the safety performance of the fire extinguisher and ensures the personal safety of the user.
