Industrial Valve Positioner Valworx Electro-Pneumatic Chemical Process Valve Positioners with SMC Solenoid Valve

Product Overview

The Valworx 5299 series is a digital smart electro-pneumatic positioner that takes a 4-20mA input and gives precise control to quarter-turn air actuators. Many customers buy it packaged with a direct-mount SMC solenoid valve for fast on/off or fail-safe operation. It's popular for upgrading pneumatic valves to smart control with diagnostics, making it a common choice in process lines where accuracy and low air use matter.
