Product Overview
The CKD EVD-3500-008AN-3 is a high-precision electro-pneumatic proportional valve engineered by CKD Corporation, a globally recognized manufacturer of advanced fluid control components. This valve operates on a dual-stage electro-pneumatic proportional principle, converting an analog electrical input signal (voltage or current) into a linearly proportional pneumatic output pressure. Unlike standard directional or on/off solenoid valves, the EVD-3500 series utilizes a precision spool and proportional solenoid actuator to achieve infinitely variable pressure regulation with exceptional repeatability and minimal hysteresis. It serves as a critical control element in closed-loop pneumatic systems, enabling precise force, speed, and position control of actuators, cylinders, and air-operated devices across demanding industrial automation processes.

Engineering Features & Advantages
- Precision Proportional Control: The EVD-3500-008AN-3 delivers infinitely variable pneumatic output pressure directly proportional to the electrical command signal, enabling smooth, stepless regulation of actuator force and speed without the abrupt transitions typical of standard solenoid valves.
- Low Hysteresis & High Repeatability: Advanced spool and sleeve geometry, combined with a high-resolution proportional solenoid, minimizes hysteresis and ensures consistent, repeatable performance across millions of operating cycles.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction that resists contamination, vibration, and thermal variation commonly encountered in factory automation environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original CKD OEM standards, ensuring drop-in replacement without modification to existing pneumatic circuits or mounting interfaces.
- Fast Dynamic Response: Optimized internal flow paths and low-inertia spool design provide rapid response to command signal changes, critical for high-speed closed-loop pressure and force control applications.
Typical Industrial Applications
The CKD EVD-3500-008AN-3 electro-pneumatic proportional valve is widely deployed in applications requiring precise pneumatic pressure or force modulation. Common industrial scenarios include: plastic injection molding machines for precise clamping force and injection pressure control; metallurgical and metal-forming presses where proportional air pressure governs forming force and stroke profiles; automated assembly and pick-and-place systems requiring gentle, programmable gripping and placement forces; and CNC machine tools and general factory automation where closed-loop pneumatic tension, web guiding
