Product Description

Summary
The JF700 electric valve positioner converts a 4–20 mA DC signal from the controller or a computer’s I/O port into pneumatic power, which drives a single‑acting or double‑acting pneumatic cylinder to produce angular or linear displacement of the control valve. It also employs a cam‑type feedback system to achieve closed-loop control, enabling the control valve to attain precise angular or linear displacement proportional to the input signal.
