Vacuum fine-tuning valve，Vacuum valve

Youdaoplaceholder0 Vacuum fine-tuning valves ‌, also known as vacuum needle valves, mainly include high vacuum fine-tuning valves, ferset micro control valves and high precision fine-tuning valves. Its main function is to precisely control the flow rate of gas introduced into the vacuum container, thereby regulating the vacuum degree within the system ‌

Working principle and application scenarios

The vacuum fine-tuning valve regulates the intake air flow through a precise fine thread design and is suitable for industries such as petrochemicals and fertilizers. Its working medium is usually air free of particulate dust and non-corrosive gas ‌

In addition, Agilent Sapphire-sealed precision trimmer valves can control extremely small flow rates (such as 1E-10 mbarl/s), are suitable for ultra-high vacuum environments with pressures as low as 1E-11 mbar and can withstand baking up to 450 ° C ‌

Structural characteristics

Vacuum fine-tuning valves usually adopt a fine-thread structure design and can precisely adjust the intake air flow. For example, Agilent 's Sapphire-sealed precision fine-tuning valve has a sapphire with an optical-grade plane inside and a set of precision position adjustment mechanisms that fine-tune through a precision fine-threaded screw and a high-magnification lever mechanism ‌

Application field

Youdaoplaceholder0 The application fields of the vacuum fine-tuning valve mainly include pharmaceuticals, food processing, semiconductor manufacturing, photovoltaic cells, vacuum coating and other fields ‌. In pharmaceutical and food processing, vacuum fine-tuning valves are used to precisely control the vacuum degree in the freeze-drying chamber, thereby affecting freeze-drying effect and product quality ‌

In semiconductor manufacturing, vacuum trimmer valves are used to control and isolate to ensure the purity and accuracy of the PROCESS ‌. In the coating process of PHOTOVOLTAIC cells, vacuum fine-tuning valve helps maintain the pressure in the vacuum chamber, promotes uniform deposition of films, improves cell conversion efficiency ‌

In addition, vacuum fine-tuning valves are also widely used in vacuum coating fields, such as decorative items, optical lenses, hard coatings for tools, etc, by precisely controlling gas flow and pressure to achieve high-quality surface treatment ‌
