Rotork YT-1000 Electro-Pneumatic Valve Positioner
Product Overview
The Rotork YT-1000 is a classic electro-pneumatic positioner for pneumatic linear and rotary actuators. It converts a 4–20 mA input signal into proportional pneumatic output pressure. Known for its simple design, good vibration resistance and easy zero/span adjustment, it is widely used in process plants for reliable valve positioning where a basic analog positioner is sufficient.
