The EP-700 (SVP-2000) electric valve positioner converts a 4-20mA DC signal from a regulator or computer IO port into pneumatic force and drives the regulating valve to achieve angular or linear displacement through a single acting or double acting cylinder. Furthermore, closed-loop control is achieved through a cam feedback system, allowing the regulating valve to achieve precise angular or linear displacement proportional to the input signal.
