PA66+30%GF fireproof V0 grade material
The venting valve is made of PA66+30%GF material. Its main function is to regulate and discharge the gas in the system, so that the fire-fighting equipment can maintain stable pressure and flow during normal operation. PA66, polyamide 66, is a thermoplastic with high strength and stiffness. After adding 30% glass fiber (GF), its mechanical properties and thermal stability are further improved, allowing the venting valve to maintain stable performance in complex and changeable working environments. The fire protection level of the venting valve is V0, which means that when burning vertically under specified test conditions, the flame will automatically extinguish within 10 seconds, and the burning drippings will not cause the filter paper to burn. These characteristics enable the venting valve to effectively prevent the spread of fire and gain valuable time for fire extinguishing work.
