FAQ
▔▔
Q1: What control signal types are supported by Bosch Rexroth Servo Proportional Valves?
A: Most models support 0–10 V, ±10 V, 4–20 mA, or PWM input signals. Some advanced models also support fieldbus communication for integration into automated systems. Selection depends on your controller and system feedback requirements.
Q2: What is the response time and bandwidth of these valves?
A: Typical response times range from 10–30 ms, with a bandwidth of up to 100 Hz depending on the model. Fast response ensures precise actuator control in high-dynamic applications such as robotics or injection molding.
Q3: What is the recommended hydraulic fluid type and viscosity range?
A: Use ISO VG 32–46 mineral oil as standard. Viscosity at 40°C should be between 20–68 cSt. For synthetic or fire-resistant fluids, consult Rexroth specifications for compatibility.
