The Rotork YT-1000 is a widely used electro-pneumatic positioner for pneumatic linear and rotary actuators. It converts a 4–20 mA control signal into proportional pneumatic output. It is known for its simple design, good vibration resistance, and easy zero/span adjustment, making it a reliable choice for general process control applications.
