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).
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).
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).
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.
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.
