Positioner is a device put into a valve to ensure that it is at correct position.an open/close operation of control valve also can be done with an i/p converter but the position of the valve can’t be confirmed. Efficiency, reducing plant operating costs, etc., we acted quickly to make our valve positioners smart.

Positioners Essentially Act As Control Systems Within Themselves (Note 2 ):
The electropneumatic positioner is attached to pneumatic control valves. The required movement is for the valve to close. Properly selected and maintained control valves increase efficiency, safety, profitability, and ecology.
Control Valves Are Subject To A Number Of Common Problems.
The valve’s stem position is the process variable (pv), the command signal to the positioner is the setpoint (sp), and the positioner’s signal to the valve actuator is the manipulated variable (mv) or output.
