FAQ
▔▔
Q1: What is the maximum flow and pressure this valve can handle?
A1: The 4WRKE16 valve supports a maximum flow of 100 L/min and a maximum operating pressure of 350 bar. Ensure system pressure does not exceed these limits to prevent damage or reduced lifespan.
Q2: How precise is the proportional control?
A2: The valve offers high-resolution proportional control with response times ≤30 ms. This allows accurate flow and position regulation of actuators in dynamic applications.
Q3: What types of hydraulic fluids are compatible?
A3: Compatible with mineral-based hydraulic oils (HLP/HVLP). Fluids should meet ISO VG 32–68 standards. Avoid fluids with high water content or poor lubrication properties.
Q4: How should the valve be installed to ensure optimal performance?
A4: Mount according to CETOP 3 / NG6 standards. Maintain clean mounting surfaces, tighten bolts to recommended torque, and ensure proper orientation to minimize internal leakage.
Q5: What are the common failure modes and maintenance tips?
A5: Common issues include solenoid burnout, spool sticking due to contamination, and internal leakage. Preventive measures: use high-quality filtration (≤25 µm), maintain oil cleanliness, and follow Rexroth's recommended service intervals.
Q6: How do I calibrate or adjust the proportional response?
A6: Use the manufacturer-provided electronic control unit or software to adjust gain, response curves, and maximum flow. Ensure adjustments comply with system specifications to avoid overshoot or instability.
