Electronic air pressure regulators with 0–10 V input are precision control devices designed for seamless integration with PLCs and automated systems in plastic tubing extrusion. These regulators deliver ultra-low pressure control (0-3" water to 0-5 psi) with high-speed response times under 0.1 second, ensuring accurate diameter control for medical, catheter, and automotive tubing manufacturing. Built with voice-coil linear motors and viscostatic damping, they maintain hysteresis-free operation across varying flow rates.
