DIRECT MOUNT POSITIONER FOR LINEAR / ROTARY MOTION OPERATION
L8A-100 electric valve positioner is a kind of receiving 4～20mA DC current signal control, which is operated by pneumatic a device to precisely adjust the valve opening. The positioner comes with an air filter pressure reducer to display the valve position opening on site (Percentage) and output feedback signal (4~20mA), directly connect the compressed air in the pressure range of 5~10kgf/cm2 to the "SUP" input interface of the positioner
