D1S2.8 150mcl one-inch valve metered dose mental stem aluminum cup inhaler valve is a precision metered inhalation device designed for medical, chemical and laboratory fields. It is designed to ensure accurate and stable dosage every time it is used, meeting the user's demand for precise control. The valve core of the valve is made of high-quality metal materials to ensure that the valve can maintain excellent durability and stability during long-term use. The design of the metal valve core not only improves the sealing performance of the valve, but also effectively prevents the problem of inaccurate dosage caused by wear. At the same time, the one-inch valve size enables the inhaler valve to adapt to a variety of standard sizes of inhaler devices, improving the compatibility and practicality of the equipment. The 150mcl quantitative design is another highlight of the product. Through precise process manufacturing, the valve can ensure that the dosage of each inhalation is within the range of 150 milliliters and microliters, thus meeting the user's demand for precise dosage. This quantitative design is particularly important in the medical field, which can ensure the accurate use of drugs or reagents and avoid the potential risks of overdose or underdose. The aluminum cap design not only enhances the overall structural strength of the valve, but also provides good sealing and corrosion resistance. The aluminum cover has a smooth surface and is easy to clean and maintain, which prolongs the service life of the product. At the same time, the lightweight design of the aluminum cover also reduces the weight of the entire inhaler device and improves the user's carrying convenience.
