8481.80.90.20/Proportional Solenoid Control Valve for Semiconductor Wafer Etching/Canada

Proportional Solenoid Control Valve for Semiconductor Wafer Etching from Canada

This electro-hydraulic proportional control valve precisely regulates gas flow in semiconductor wafer etching chambers based on electronic signals from a PLC controller. It falls under HTS 8481.80.9020 due to its design for proportional operation via control device signals, optimized for cleanroom environments in chip fabrication. Used in plasma etching tools to maintain exact pressure differentials.

Import Tips

• Verify actuator type and signal compatibility documentation to confirm proportional operation classification under 8481.80.9020

• Include cleanroom certification and material compatibility certificates (e.g

• for HF gases) to avoid reclassification as semiconductor-specific machinery
