FAQ:
1. Q: How to select the right Rexroth electro-hydraulic valve for my application?
A: Consider operating pressure, flow rate, control precision, input signal type, environmental conditions (temperature, contamination), and compatibility with hydraulic fluid.
2. 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 specifications for details.
3. 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.
4. 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).
5. 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 lubrication.
