2. Hydraulic Technical Data

Rated Flow: 120 L/min (ΔP=35bar per spool land); Max overflow ≈150 L/min

Working Pressure:

P/A/B main ports: Max 350 bar (5000 PSI)

Internal T/Y drain port: Max 210 bar (3000 PSI)Moog Inc.

Pilot arrangement: Internal pilot oil supply(X), internal drain(Y), no external pilot pipeline needed

Working fluid: Mineral hydraulic oil DIN51524, cleanliness requirement NAS 6~7; Working temp: -20℃ ~ +70℃

Net weight: ~5.7kg

Fail-safe: De-energized → spring mechanically returns spool to neutral mid-position, locking actuator position

3. Electrical Parameters

Power supply: DC24V (18~32VDC), total power consumption ≤35WMoog Inc.

Control input: Standard differential ±10VDC analog signal; optional ±10mA current inputMoog Inc.

Step response (210bar supply, full stroke 0→100%): 7~9ms, high dynamic responsiveness

Connector: Standard 12-pin round aviation plug; In-built protection: reverse polarity, overcurrent, short-circuit protection; EMC compliant per EN61000Moog Inc.

Protection grade: Plug IP65, valve body IP54

4. Structural Features

ServoJet jet-pipe pilot: Higher anti-contamination than nozzle-flapper structure, low failure rate, stable zero drift performanceMoog Inc.

Internal non-contact LVDT sensor collects real-time spool displacement, forms inner closed-loop inside valve, linearity ≤±0.2%FSMoog Inc.

Side-mounted zero trim potentiometer for on-site zero offset calibration without disassembly

Zero-lap spool design: Excellent static accuracy for closed-loop position/force control

5. Typical Application

Material fatigue test rig, multi-axis hydraulic test bench

Medium tonnage hydraulic forming press, automobile component compression test equipment

Medium-flow turbine auxiliary EH regulation system, precision hydraulic position servo system

6. Installation & Maintenance Tips

Install on standard ISO05 manifold; keep away from high temperature, splash water and dense oil mist

Install ≥3μm high-pressure filter at P inlet to protect ServoJet pilot nozzle from blocking

Separate shielded signal wire and power cable in different wiring ducts to avoid EMI interference

Calibrate valve zero point annually; check seal leakage every half year
