The working principle of the L-031 L-shaped air freshener aerosol metering valve is based on pressure control and flow regulation. When the valve stem is pressed, the channel in the valve body is opened, and the high-pressure gas in the tank pushes the liquid through the valve and nozzle to form a fine mist spray. This design not only ensures the uniform distribution of the air freshener, but also improves the efficiency of the product. The L-031 L-shaped metering valve performs well. Its high metering accuracy can ensure that the dosage of each spray remains consistent, thus providing users with stable use effects. The valve has excellent sealing performance, effectively preventing gas leakage and extending the service life of the product. In addition, the metering valve also has good compatibility and adaptability, and can adapt to a variety of air freshener tanks of different specifications and types, providing users with more choices.
