Product Description
CHX(EP)-724AH Electric Valve Positioner
Product Overview

The CHX(EP)-724AH electric valve positioner converts 4-20 mA DC signals from regulators or computer I/O ports into pneumatic force, driving regulating valves via single or double-acting cylinders to achieve precise angular or linear displacement. Through a cam feedback system, it enables closed-loop control for accurate proportional positioning.
