KGP5000 series smart valve positioner is a control device mounted on the pneumatic actuator for control valve, which positions a control valve according to a 4 to 20mA electric input signal from a higher-level control system or a control device.
Position feedback control system which receives feedback signal mapped to the desired valve travel and compares both input signal and feedback signal enables accurate positioning of a control valve.
In addition, it is possible to use this positioner in order to operate various types of pneumatic actuator such as single and double acting, linear and rotary motion actuators.
Furthermore, the positioner utilizing digital techniques performs the functions of advanced PID controller, local user interface using LCD, diagnostics utilizing sensing techniques with potentiometers and internal pressure sensors.
Such features enable an easy installation and calibration, an effective monitoring and an efficient process management relevant to operations and maintenance.
