D1VW020BNJDLJ5 Parker Solenoid Directional Valve

Product Overview

The D1VW020BNJDLJ5 and D1VW030BNJWTI5N are Parker D1VW series direct-operated solenoid directional valves. Featuring wet-armature solenoids, they conform to DIN NG06 / CETOP 03 / NFPA D03 mounting standards, with a maximum operating pressure of 350 bar (ports P/A/B) and maximum flow up to 80 L/min. These valves offer true interchangeability as drop-in replacements for original Parker units without manifold modifications. Every valve undergoes precision machining and 100% simulated duty-cycle testing to ensure reliable shifting, low pressure drop and long service life for industrial hydraulic direction control.

Key Technical Advantages

1. Wet-armature solenoid design – Coils can be replaced under pressure, providing controlled temperature rise, extended life and good environmental protection.
2. High-pressure high-flow capability – 350 bar operating pressure and up to 80 L/min flow meet the majority of industrial hydraulic requirements.
3. True interchangeability and standard interfaces – Fully compliant with ISO 4401 / CETOP 03 mounting pattern, enabling direct replacement of original Parker valves and minimizing modification costs.
4. Precision machining and low leakage – High-accuracy spool fit delivers low pressure drop and minimal leakage, verified by 100% duty-cycle testing.

Application Areas

Ideal for injection molding machines, die-casting equipment, machine tools, hydraulic power units, mobile machinery, metallurgical plants and any industrial hydraulic system requiring reliable directional control.

Expert Maintenance Tips

Ensure the manifold surface is flat and clean and tighten bolts to the specified torque; confirm voltage match and proper earthing before wiring; maintain fluid cleanliness at ISO 4406 18/16/13 or better; periodically check solenoid temperature rise and shifting action; after prolonged storage, energize the valve to verify free spool movement.
