Displacement accuracy control of the valve needle
Release Date:
2025-08-08
The valve needle uses a plug-in installation structure linked with a lever drive mechanism, achieving millimeter-level displacement precision control through the extension and retraction of the pressure cylinder piston rod. Its conical surface taper angle is designed between 45° and 75°, with the tip diameter 4% larger than the valve body discharge end to achieve dynamic sealing.
