Our Positioners include
Pneumatic Positioners - A Pneumatic Positioner is a device that controls a valve actuator by using a pneumatic signal (typically 3-15 psi) to accurately position the valve according to the control input. The main types include single-acting pneumatic positioners (for spring-return actuators) and double-acting pneumatic positioners (for actuators requiring air pressure in both directions). They are widely used in industries such as chemical, oil & gas, and power plants for precise valve control, ensuring accurate flow, pressure, or level regulation in automated process systems.
Electro-Pneumatic (I/P) Positioners - An Electro-Pneumatic (I/P) Positioner is a device that converts an electrical control signal (typically 4-20 mA) into a proportional pneumatic output to accurately position a valve actuator. The main types include single-acting I/P positioners (for spring-return actuators) and double-acting I/P positioners (for actuators requiring air pressure in both directions). They are widely used in industries such as chemical, oil & gas, and power plants for integrating electric control systems with pneumatic actuators, enabling precise automated process control.
Smart / Digital Positioners - A Smart/Digital Positioner is a device that uses digital electronics to control valve actuators, providing precise positioning along with self-calibration, diagnostics, and communication via protocols like HART, Foundation Fieldbus, or Profibus. The main types include digital pneumatic positioners (control pneumatic actuators) and electro-digital/electric positioners (control electric actuators). They are widely used in industries such as chemical, petrochemical, and power plants for advanced process control, predictive maintenance, and improved operational efficiency.
