Piston-Type Hydraulic Accumulator from China
Piston-type hydraulic accumulators use a movable piston to separate hydraulic fluid from pre-charged gas, ideal for high-pressure applications in crystal growers for semiconductor boule production. Classified under HTS 8479.89.95.65 as hydraulic accumulators within other machines for semiconductor manufacturing and testing. They provide pulsation dampening and emergency power in wafer fabrication equipment.
