Products Overview
Lintelligent Positioner For Pneumatic Control Valve Smart Digital Valve Positioner
The electric valve positioner is a device that accepts 4-20mA DC current signal control and accurately adjusts the valve opening through the pneumatic actuator. The positioner comes with an air filter pressure reducer to display the valve opening on site and the output signal feedback. Directly connect the compressed air in the pressure range of 5-10kgf/cm to the positioner "SUB" input interface
