Product Advantages

Core Positioning

Mid-sized pilot-operated proportional valve with 10V analog control and integrated OBE, balancing flow capacity and precision for medium-scale hydraulic systems. Engineered for industrial equipment requiring consistent performance across dynamic load conditions, such as plastic molding machines and automated assembly lines.

10V Control & OBE Intelligence

A1 interface with ±10V command input and dedicated reference potential pin, ensuring noise-free signal transmission. OBE features built-in differential amplifier and power supply unit (24 VDC, 19–36 V range), reducing external component count. Adjustable ramp time (0–2.5 s) eliminates system shock during start-stop cycles.

Flow & Pressure Capabilities

Rated flow 125–180 l/min (Δp=5 bar), maximum flow 460 l/min. Main valve ports A/B/P rated 350 bar, pilot supply 100 bar (internal), external return 250 bar. Pilot flow 5.5 l/min enables fast spool actuation, while pressure-compensated main stage maintains flow stability despite pressure fluctuations.

Structural & Installation Robustness

Weighs 14.0 kg, ISO 4401-07-07-0-05 porting pattern (ports A/B/P/T Ø20 mm). Requires 2 M6 x 60 + 4 M10 x 60 fixing screws (12.2–75 Nm tightening torque). Cable length up to 30 m with plastic mating connector (or 40 m with metal connector) – shielding connected to PE for EMC compliance.

Fluid Compatibility & Longevity

Works with mineral oils (HL/HLPD), biodegradable HEES, and flame-resistant HFDU (FKM seals). Viscosity range 20–380 mm²/s, hydraulic fluid temperature -20~+80°C. ISO 4406 18/16/13 (pilot) and 20/18/15 (main valve) cleanliness requirements prevent component wear.

Safety & Operational Features

Spring-centered main spool for fail-safe neutral position. Optional seawater-resistant coating (J version) for marine or offshore applications. Locking pin secures valve body to subplate, preventing vibration-induced loosening.

Industry Application Fit

Perfect for medium hydraulic presses, plastic injection molding machines, and automated assembly lines. Excels in automotive component manufacturing, packaging machinery, and industrial robots where 10V precision control and mid-range flow capacity are critical.
