Model Interpretation

D662: NG16 Installation, Jet Pipe Pilot Built-in Electronic Servo Valve Series

4013: Basic Specification Code, ΔP = 35bar, Single-sided Pressure Difference Rated Flow Rate 190L/min, Standard Valve Core Stroke, Internal Return Oil + Independent Y Leakage Oil Port (4010 = 75L/min, 4011 = 100L/min, 4012 = 140L/min, 4013 = 190L/min); The subsequent suffix DxxHABF6VSX2HA coding rule is the same as the entire 4010 series, defining the neutral function, pressure rating, sealing, electrical terminals, and control signals.

Electrical parameters

Power supply: DC24V (18~32VDC wide voltage range), total power consumption ≤ 360mA

Standard control signals: ±10VDC differential voltage, optional ±10mA, 4~20mA current input

Electromagnetic compatibility: EN55011 industrial EMC certification by Moog Inc.

Interface and communication configuration

Hydraulic installation: ISO4401-07 standard installation base plate, P inlet, T internal leakage return oil, AB load oil ports, Y independent external leakage oil port

Electrical interface: 7-pin round aviation plug, integrated power supply, command, valve core feedback terminals, control lines need to be shielded and single-ended grounded

Control mode: Pure analog closed-loop, no bus communication interface Core function

Built-in LVDT valve core with full closed-loop, onboard circuit automatically compensates for zero drift, excellent high and low temperature stability

ServoJet jet pipe pilot, superior to nozzle baffle in resistance to oil impurities, long-term failure rate is low

D02 standardly equipped with O-type neutral position, power-off spring returns to neutral lock, neutral position maintains pressure sealing

High flow rate compatible with high-speed injection, large load cylinder for rapid movement, injection molding machine controls four actions of injection, pressure holding, back pressure, and release with one valve. Applicable scenarios

Closed-loop injection system for medium and large-scale injection molding machines, locking system for heavy die-casting machines, high-speed injection, hydraulic pressurization for medium-thick plate rolling machines, heavy-duty material testing machines, large-scale forging hydraulic units.

Operation and maintenance instructions

Install a 3μm precision high-pressure filter for the high-pressure oil intake. Replace the first set of filter elements 15 days after the new machine is put into operation.

Separate the power supply line and control shielding line for wiring. The shielding cable should be grounded at only one point in the control cabinet.

The factory performs zero-point calibration. Only minor electrical fine-tuning is allowed at the site. Do not disassemble the pilot and main valve core components.

Fully seal and block all oil ports when idle. Store in a dry and dust-proof environment for storage to prevent the sealing components from getting damp and aging.
