Product Advantages

Core Positioning

Ultra-compact pilot-operated proportional valve with integrated on-board electronics (OBE) and 10V analog control, tailored for miniature hydraulic systems. Delivers pinpoint flow direction and magnitude regulation, ideal for space-constrained precision equipment where responsiveness and low power consumption are critical.

10V Control Precision & OBE Advantages

A1 interface with ±10V differential command input (input resistance >100 kΩ) and reference potential grounding. OBE integrates ramp generator (0–2.5 s adjustable rise/fall time) and undervoltage detection, ensuring smooth, shock-free switching. Hysteresis <6% and low zero drift guarantee consistent positioning accuracy across -20~+50°C ambient temperature.

Flow & Pressure Performance

Rated flow 25–85 l/min (Δp=5 bar/control edge), maximum flow 170 l/min. Main valve ports A/B/P support 350 bar max operating pressure, with internal pilot supply (100 bar) and external return (315 bar). Pilot flow 3.5 l/min ensures rapid pilot spool response, while pressure compensation minimizes flow variation under load.

Structural & Installation Highlights

Weighs 8.0 kg, ISO 4401-05-05-0-05 porting pattern for subplate mounting. Requires 4 M6 x 45 fixing screws (13.5–15.5 Nm tightening torque). 3-pole (K4) or 7-pole (K31) connectors with LiYCY 7×0.75 mm² cable (up to 20 m) – EMC-compliant installation with double-ended shielding.

Fluid Adaptability & Reliability

Compatible with mineral oils (HL/HLP), biodegradable fluids (HETG/HEES), and flame-resistant HFC (NBR seals). Viscosity range 20–380 mm²/s (30–46 mm²/s recommended), hydraulic fluid temperature -20~+80°C. IP65 protection and 95% relative humidity tolerance (no condensation) enhance durability in harsh environments.

Safety & Operational Flexibility

Spring-centered main spool returns to neutral on de-energization, preventing unintended movement. Optional concealed manual override (N9) enables emergency operation without power. Internal leakage inherent to design is minimized via precision-machined spool, with ISO 4406 18/16/13 fluid cleanliness requirement to extend service life.

Industry-Specific Applications

Perfect for miniature hydraulic power units, precision robotic actuators, and medical device hydraulics. Excels in electronic component assembly machines, small-scale testing equipment, and lab automation systems where compact size, 10V control compatibility, and low noise operation are non-negotiable.
