Frequently Asked Questions
Q: Can Rexroth electro-hydraulic valves be used in high-temperature environments?
A: Most models operate reliably between -20°C to 80°C; high-temperature versions (up to 120°C) are available for extreme industrial settings.
Q: How often should Rexroth electro-hydraulic valves be maintained?
A: Routine inspection every 6-12 months (or 500 operating hours); frequency increases in harsh conditions (contaminated fluids, high pressure/temperature).
Q: What are the common causes of Rexroth electro-hydraulic valve malfunctions?
A: Hydraulic fluid contamination, electrical signal issues, worn seals, incorrect wiring, pressure spikes, or inadequate lubriion.
Q: How to troubleshoot a Rexroth electro-hydraulic valve that fails to actuate?
A: Check power supply/wiring, verify input signal (use a multimeter), inspect for fluid contamination/clogs, and test for stuck spools or damaged solenoids.
Q: Are Rexroth electro-hydraulic valves compatible with biodegradable hydraulic fluids?
A: Yes--most models work with biodegradable oils (e.g., vegetable-based, synthetic esters); confirm compatibility with the fluid manufacturer and Rexroth's guidelines.
Q: What is the response time of Rexroth electro-hydraulic valves?
A: Proportional valves: 10-50 ms; servo valves: <5 ms (for high-precision appliions); response time depends on valve size and control type.
