FAQ
▔▔
What is the difference between a proportional valve and a servo valve?
Proportional valves offer continuous control with good accuracy and robustness, while servo valves provide higher precision and faster response but at higher cost and sensitivity to oil contamination.
Can proportional Rexroth valves replace standard directional valves?
Yes, in applications requiring variable speed, pressure, or position control. However, system design and electrical control must support proportional operation.
What signal types are supported by Rexroth proportional valves?
Most models support 0–10 V, ±10 V, or 4–20 mA signals, depending on the valve and amplifier configuration.
Are Rexroth proportional valves suitable for mobile hydraulics?
Yes. Many Rexroth proportional valves are designed specifically for mobile equipment, offering vibration resistance and wide temperature tolerance.
How do I ensure correct valve selection?
Key factors include system pressure, required flow rate, control signal type, mounting interface, and application duty cycle.
