FAQ:

1. Q: What is the service life of a typical Rexroth electro-hydraulic valve?
A: 10,000-20,000 operating hours (standard conditions); proper maintenance and clean fluid can extend life to 30,000+ hours.

2. Q: How to prevent contamination from damaging Rexroth electro-hydraulic valves?
A: Use high-quality hydraulic filters (10 µm or finer), regularly replace fluid, keep reservoirs sealed, and avoid mixing different fluid types.

3. Q: Are replacement parts available for aging Rexroth electro-hydraulic valves?
A: Yes—Rexroth supplies genuine replacement parts (seals, solenoids, spools, coils) globally; contact authorized distributors for fast sourcing.

4. Q: How does temperature affect the performance of Rexroth electro-hydraulic valves?
A: Low temperatures thicken fluid (slower response); high temperatures degrade seals and reduce fluid viscosity (leaks, reduced control precision).

5. Q: Can Rexroth electro-hydraulic valves be used in mobile hydraulic systems?
A: Yes—Rexroth offers compact, rugged models (with IP65/IP67 protection) designed for mobile equipment (excavators, tractors, trucks).

6. 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).
