Key differences from previous models (8312/8322)

8332: 6 cores + PE, LVDT closed loop, high-stability throttling, super EMC, FPM high-temperature sealing → top accuracy + high-temperature + strong interference

8322: 6 cores + PE, LVDT closed loop, special throttling, enhanced EMC, NBR sealing → high accuracy + strong interference

8312: 6 cores + PE, LVDT closed loop, standard throttling, standard EMC, NBR sealing → standard high accuracy Structural features

Two-stage ServoJet jet pipe pilot: anti-pollution, long service life, high reliability

Integrated 24V drive + LVDT closed-loop + EMC enhanced: no need for external amplifier, highest accuracy, strongest anti-interference. Moog Inc.

Highly stable throttling + FPM high-temperature sealing: zero leakage at zero position, good high-temperature stability, suitable for long-term high-temperature / steady-state conditions

Typical applications

Metallurgy: high-temperature rolling mills, continuous casting machine tension/thickness control (high temperature + strong interference)

Material testing: high-frequency fatigue test, long-term static loading (high repeatability + low leakage)

Injection molding / die-casting: precise closed-loop control (high-temperature molds + strong electrical environment)

Aerospace / military: ground simulation test, high-precision electro-hydraulic servo system
