In equipment such as injection molding machines, die casting machines, and forging machines, 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.

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.
