Positioner L8A-100RDiPL

L8A-100RDM L8A-100LSMNon feedback type electrical valve positioner

The L8A-100RDiPL angle stroke feedback pneumatic control valve positioner L8A-100 series electrical valve positioner is a device that receives a 4-20mA DC current signal from the control system and adjusts the valve opening through a pneumatic actuator. The valve positioner comes with an air filter pressure reducing valve, which displays the on-site valve position opening (percentage) and outputs feedback signals (4~20mA). Simply connect compressed air with a pressure range of 5~10kgf/cm2 to the SUP input interface of the positioner. The feedback type valve positioner is equipped with an LCD screen display, which can clearly see the input and output opening signals.
