D1VW002 Parker Solenoid Directional Control Valve 350bar

Product Overview:

The D1VW series (including specific part codes such as D1VW002KNTWXC010, D1VW001FNJW91, and D1VW002CNJW91) features highly advanced, direct-operated wet armature solenoid directional control valves. Serving as a foundational control component in standard NG06 (CETOP 03) sizes, it utilizes a solenoid to shift the internal spool, accurately altering fluid direction to start, stop, or reverse hydraulic actuators. Fully benchmarked against the highest original Parker manufacturing specifications, our D1VW series delivers exceptional fluid dynamic performance and minimal pressure drop. Every valve guarantees 100% seamless drop-in interchangeability and is subjected to rigorous 100% simulated full-load operational testing prior to dispatch. This ensures absolute reliability even under extreme conditions and high-intensity, continuous cycling environments.

Key Technical Advantages:

1. High-Efficiency Wet Armature Design: The fully enclosed wet armature solenoids operate directly within the hydraulic fluid. This design utilizes the oil for excellent internal heat dissipation and lubrication, eliminating dynamic seal wear, drastically reducing mechanical friction, and maximizing service life.

2. 100% Seamless Interchangeability: The mounting footprint strictly complies with ISO 4401 standards. It serves as a direct, bolt-on replacement for original Parker D1VW series valves, requiring zero modifications to existing subplates or manifolds.

3. Ultra-Low Pressure Drop: The internal valve body features expanded, CFD-optimized flow channels. Even when subjected to maximum flow rates of 80 L/min, it maintains an exceptionally low pressure drop, effectively minimizing system heat generation and improving overall energy efficiency.

4. Military-Grade Precision & Fatigue Resistance: The internal spools are machined from premium alloy steel, undergoing deep carbonitriding and micron-level honing for minimal sliding resistance. Combined with powerful solenoid force, the valve executes up to 15,000 shifts per hour without hesitation or sticking.

Application Areas:

• Injection Molding Machines: Providing high-frequency, precise directional control for clamping cylinders, injection carriage movements, and ejectors.

• CNC Machining Centers: Actuating tool magazines, tailstocks, and workpiece clamping cylinders in continuous cutting environments.

• Automated Press Lines: Serving as the core logic control for rapid lifting and lowering of main and auxiliary cylinders in heavy presses.

• Marine & Mobile Hydraulics: Highly suitable for offshore and mobile circuits demanding uncompromised response speeds and continuous duty capability.

Expert Maintenance Tips:

• Temperature Caution: The solenoids are rated for 100% continuous duty (100% ED). However, after prolonged continuous operation, the coil surface temperature can reach up to 150°C. Never touch the coil directly with bare hands during maintenance to prevent severe burns.

• Back Pressure (Port T) Management: Closely monitor the return line (Port T) pressure limits (210 bar for DC / 140 bar for AC). Excessive back pressure caused by return line restriction increases shifting resistance, hampers valve sensitivity, and can ultimately blow out internal seals.

• Manual Override Usage: In the event of a power outage or electrical failure, the valve can be manually actuated. Use a blunt, non-sharp tool to depress the manual override button located at the end of the solenoid tube. This forces the spool to shift mechanically, allowing the actuator to be safely retracted or reset.
