Frequently Asked Questions
Q: What is the maximum operating pressure of Rexroth electro-hydraulic valves?
A: It varies by model--ranging from 210 bar (standard) to 350 bar (high-pressure variants); refer to the valve's technical specifiions for details.
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.
