ELECTRO PNEUMATIC SMART POSITIONER
“aline” Make Electro Pneumatic Smart Positioner is an advanced digital valve positioner designed to provide highly accurate, stable, and intelligent control of pneumatic control valves. It receives a 4–20 mA input signal from the control system and precisely regulates the pneumatic output pressure to position the actuator according to the desired valve opening. With integrated microprocessor technology, automatic calibration, self-diagnostics, and continuous position feedback, the Smart Positioner ensures superior process control, increased efficiency, and reduced maintenance.
Suitable for both Rotary and Linear Pneumatic Actuators, the ALINE Smart Positioner delivers exceptional accuracy, fast response, and reliable performance in the most demanding industrial environments. Its robust weatherproof housing and intuitive digital interface make installation, configuration, and maintenance simple and efficient.
The Smart Positioner is widely used in Control Valves, Ball Valves, Butterfly Valves, Globe Valves, Angle Seat Valves, Diaphragm Valves, Oil & Gas, Chemical Processing, Power Plants, Water Treatment, Pharmaceutical, Food & Beverage, Steel Plants, Paper Mills, and General Process Automation.
