FAQ:

1. Q: What is the difference between proportional and servo-type Rexroth electro-hydraulic valves?
A: Proportional valves offer variable flow/pressure proportional to input signals (cost-effective for most industrial uses); servo valves provide ultra-high precision (for aerospace, robotics).

2. Q: How to wire a Rexroth electro-hydraulic valve correctly?
A: Follow the wiring diagram in the product manual—connect power (positive/negative), signal wires (4-20mA/0-10V), and ground; avoid reverse polarity.

3. Q: What are the signs that a Rexroth electro-hydraulic valve needs to be replaced?
A: Persistent leaks, inconsistent performance, slow response, inability to reach set pressure/flow, or frequent solenoid failures.

4. Q: Does Rexroth provide technical support for electro-hydraulic valve installation?
A: Yes—Rexroth offers online resources (manuals, videos), technical hotlines, and on-site support via authorized partners worldwide.

5. Q: How to adjust the flow rate of a Rexroth electro-hydraulic valve?
A: Modify the input signal (increase/decrease 4-20mA/0-10V) or use built-in flow adjustment screws (for manual fine-tuning on select models).
