Fisher Controls International LLC 41B8558X012 Positioner

Fisher 41B8558X012 Positioner is a pneumatic actuator accessory designed to mount with Baumann 26200 Control Valves, forming a precise valve-control package within Emerson’s Fisher–Baumann lineup. The unit operates on a 3 to 15 psi pneumatic signal and is intended to be used with a separate I/P transducer to convert an electrical control signal into the air pressure that moves the valve actuator, enabling accurate and repeatable positioning in process-control loops. The 26200 valve belongs to Baumann’s 26000 family and is designed for use with Baumann actuators on sliding-stem control valves, a pairing that the 41B8558X012 positioner is built to support. In field installations, this combination provides dependable valve travel and responsiveness to process changes, which is essential for maintain­ing tight control over flow in hostile or high‑demand environments found in chemical processing and energy sectors. The part numbers themselves reflect a designed integration within Emerson’s Fisher and Baumann products, aligning a Fisher positioner with Baumann actuators to streamline installation and ensure consistent actuation performance.
