FAQ
▔▔
1. What is the difference between Atos ON/OFF directional valves and proportional valves?
Atos ON/OFF directional valves (such as the DHI or DKE series) operate in binary states-fully open or fully closed-shifting fluid flow from one port to another. Atos proportional valves (such as the DPZO series) vary flow volume or fluid pressure smoothly and continuously in proportion to an electrical input signal, enabling precise control over speed, acceleration, and position.
2. How do I choose between integrated electronics (AEB/AES) and separated electronics (E-MI) for Atos valves?
Integrated digital drivers (AEB/AES) are factory-calibrated directly on the valve, simplifying wiring, reducing electromagnetic interference, and providing plug-and-play installation. Separated drivers (E-MI) are preferred when the ambient environment near the valve exceeds high temperature limits, experiences extreme vibration, or when space constraints around the manifold are tight.
