L8A-100 2021001
Description
L8A-100 electric valve positioner is a device that receives 4 ~ 20mA DC signal control and precisely adjusts the valve opening through pneumatic actuator. The positioner is equipped with an air filter pressure reducer to display the opening (percentage) of the valve position and output feedback signal (4 ~ 20mA). The compressed air of the pressure of 5~10kgf/cm² can be directly connected to the "SUP" input interface of the positioner.
