Product Overview
The CKD EVD-3500-008AN is a high-precision electro-pneumatic proportional valve engineered by CKD Corporation for accurate, continuously variable control of air and neutral gas flow in industrial automation systems. Unlike conventional on/off solenoid valves, this unit modulates its spool position proportionally to an analog electrical command signal (voltage or current), delivering stepless pressure and flow regulation that closely tracks the reference input. The EVD-3500 series is widely deployed as a core control element in electro-pneumatic regulation loops, where it functions as a pressure or flow control valve rather than a pump or fluid power source. Its compact body, low hysteresis, and fast dynamic response make it suitable for tension control, force regulation, and velocity modulation tasks in demanding process environments.
