Target pucks for valve actuators are specialized components used in industrial valve systems, typically associated with brands like Flowserve, Emerson, or Rotork. These brands are global leaders in valve automation, with Flowserve headquartered in the USA, Emerson also based in the USA, and Rotork originating from the UK. Target pucks serve as visual or sensor-based alignment indicators for valve actuators, ensuring precise positioning in industries such as oil & gas, water treatment, and power generation. They are often part of modular actuator systems, enabling efficient maintenance and calibration. Companies like Radwell and Grainger distribute these components as part of their industrial automation portfolios.
