8481.10.00.20/Hydraulic Pressure Reducing Valve for Semiconductor Wafer Crystal Pullers/China

Hydraulic Pressure Reducing Valve for Semiconductor Wafer Crystal Pullers from China

This hydraulic pressure reducing valve regulates fluid pressure in Czochralski crystal pullers used to grow monocrystalline silicon boules for semiconductor wafers. It falls under HTS 8481.10.0020 as a hydraulic fluid power type pressure-reducing valve essential for precise control in semiconductor manufacturing equipment. The valve maintains stable hydraulic pressure during the crystal growth process to ensure boule uniformity.
