D20T2.8 50mcl mental stem 20mm Metering Valves with Aluminum cup is a fluid control component with precise design and efficient functions, designed for occasions requiring accurate metering and stable flow control. The metering valve adopts a metal stem structure with an aluminum cover body, which not only ensures the durability and stability of the product, but also provides good sealing performance and corrosion resistance. The core component of the metering valve, the valve stem, is made of high-quality metal materials with high strength, high hardness and good wear resistance. It can withstand large fluid pressure and mechanical stress, ensuring that the valve can maintain accurate metering and stable flow control during long-term use. At the same time, the metal valve stem also has good thermal conductivity, which helps to quickly dissipate heat and avoid the normal operation of the valve due to excessive temperature. The aluminum cup gives the metering valve a light and beautiful feature, while the corrosion resistance of aluminum also ensures that the valve can still maintain good working condition in harsh environments. The connection method between the aluminum cup and the valve body has been optimized to ensure the reliability of the seal and effectively prevent fluid leakage. The single metering capacity is 50mcl, which is suitable for a variety of fluid media, such as liquids, gases, etc. Its precise metering ability and stable flow control performance make this metering valve widely used in chemical, pharmaceutical, food, beverage and other industries.
