Micro valve needle valve sleeve precisely controls insulin delivery rate (0.1-100μL/h), matching patient blood glucose fluctuations, requiring low leakage (<0.1μL/min) and long lifespan (>5 years).
In gasoline direct injection (GDI) and diesel common rail systems, the valve needle and valve sleeve form a high-speed switching valve that precisely controls the fuel injection quantity, timing, and atomization effect, directly affecting engine combustion efficiency, emission performance, and power output. For example, injectors from suppliers such as Bosch and Delphi use this type of structure.
In equipment such as injection molding machines, die casting machines, and forging presses, the valve needle and valve sleeve serve as the core of proportional valves or servo valves. They control fluid pressure/flow through electrical signals to achieve precise synchronization of mold opening/closing, ejection, and other actions, thereby improving product qualification rates.
During the assembly of mobile phone camera modules, the needle valve and valve sleeve are used in the dispensing machine to precisely control the amount of UV glue or hot melt adhesive dispensed (0.01-1mL/s), preventing yield loss caused by glue overflow or shortage.
In the hydraulic/pneumatic joints of collaborative robots (Cobots), miniature needle valve sleeves are used for flow regulation, achieving lightweight, high-response motion control that meets human-robot collaboration safety standards.
