Abstract
An insert arrangement may be used with a control valve for adjusting a process fluid flow of a process plant (e.g., a chemical plant, a power plant, a food processing plant) having a valve housing, a housing cover and an actuator. The insert arrangement may include an annular mounting flange which can be inserted between the valve housing and the housing cover. An insert sleeve may be reversibly attachable or attached radially on the inner side of the mounting flange for guiding the actuator.
