FIELD: instrument making.
SUBSTANCE: described are a transfer station, assembly and method for providing bypass of adjustment device in active control circuit. Actuator mechanism assembly according to one embodiment comprises a pneumatic actuator and a transfer station. Transfer station includes a body defining flow paths that enable fluid to flow between a supply pressure source, a valve positioner and pneumatic actuator, and between supply pressure source and pneumatic actuator to bypass valve positioner without disrupting a process loop including said valve positioner. Transfer station also includes fluid flow control devices to control fluid flow through flow paths.
EFFECT: technical result is increased accuracy of control.
