FAQ
▔▔
Q: What control signals do Parker Servo Proportional Control Valves accept?
A: These valves typically accept 0-10 V voltage or 4-20 mA current signals, depending on the model. Some advanced versions support PWM (pulse-width modulation) or digital CAN bus input for integration with automated control systems. Proper signal conditioning ensures accurate valve response and prevents oscillation.
Q: How does the valve maintain precision under varying load conditions?
A: Parker Servo Proportional Valves use a closed-loop servo mechanism with a feedback spool position sensor. The valve continuously adjusts the spool position based on the input signal and actual flow/pressure, compensating for load changes and ensuring consistent output.
