Product Advantages
1. Small-Flow High-Precision Voltage
Control
As a pilot-operated proportional directional valve with electrical position feedback, it integrates dual inductive position transducers (pilot + main stage) and OBE electronics, achieving micron-level flow regulation. The A1 interface supports ±10V voltage input/output with an input resistance of 100 kΩ, ensuring stable signal transmission. With hysteresis ≤0.1% and response sensitivity ≤0.05%, it maintains exceptional precision across rated flows of 25/50/100 l/min (Δp=5 bar/control edge), paired with linear "L" or fine-control "P" flow characteristics.
2. Compact Integration & Flexible Pilot Oil Supply
Compliant with the ISO 4401-05-05-0-05 porting pattern, the valve enables standardized subplate mounting with a lightweight 8.7 kg structure, ideal for space-constrained installations. Built-in OBE electronics and 24VDC wide-range power supply (18–35VDC) simplify wiring. It offers multiple pilot oil supply modes (external/internal supply/return combinations) and NBR/FKM seal compatibility with mineral oil, HEES biodegradable oil, and HFC flame-resistant oil, adapting to light-duty scenarios such as small machinery and auxiliary hydraulic circuits.
3. Robust Durability for General Industrial Environments
Boasting an IP65 protection rating (with properly mounted connectors), the valve operates stably in ambient temperatures of -20℃ to 50℃ and relative humidity up to 97% (cyclic damp heat). It withstands a maximum operating pressure of 350 bar (ports A/B/P) and 315 bar (external pilot return), with excellent resistance to vibration (10–2000Hz, 10g) and shock (15g, 11ms). The hydraulic fluid cleanliness requirement of ISO 4406 Class 18/16/13 extends service life in standard industrial conditions.
4. Safety-Focused & Low-Maintenance
Design
The spring-centered main spool resets to central position upon power failure, while automatic pressure compensation in control chambers prevents uncontrolled movements. Integrated undervoltage detection, cable break detection, and zero-point calibration (±1% ex works) enhance operational safety. The detachable 6-pole + PE mating connector and standardized ISO 4762 M6 mounting screws (13.5 Nm tightening torque) simplify maintenance, reducing downtime for light-duty equipment.
