FAQ
▔▔
What is the internal control principle of the D637 direct drive servo valve?
The D637-1022-0001 uses a linear force motor directly coupled to the spool. The input electrical signal (typically ±10 V) generates a proportional electromagnetic force, moving the spool without a pilot stage. An internal position feedback sensor continuously monitors spool position and adjusts it in a closed-loop system. This ensures high accuracy, minimal hysteresis, and excellent repeatability.
Can the D637-1022-0001 be used in feedback control loops?
A: Yes, it is optimized for closed-loop position, velocity, and force control systems, providing stable and predictable performance when paired with high-quality sensors and controllers.
