    Abstract: Exemplary embodiments are directed to apparatus, systems and methods used in connection with a needle valve device operating in a pressurized flow system. The apparatus, systems and methods provide for automatic positioning of a needle relative to a seat in the needle valve device to provide consistent calibration with minimal user interaction after a maintenance event or upon a start-up of the pressurized flow system. The apparatus, systems and methods utilize a calibration collar secured to a shaft of an actuator within the needle valve device. The calibration collar includes one or more locking mechanism and a spring.
