    The depiction of the products may differ from the actual specific design.

    Please consider the technical attributes and Data Sheets.

    Type Description

    The Type 2051 pneumatic rotary actuators are pneumatic linear piston actuators. They are low-maintenance and are available with single-acting or double-acting actuators. The linear movement of the piston due to the pilot air causes a 90º rotation of the connected valve. Actuator-valve coupling is made via a universal ISO 5211 mechanical interface. The status of ball or butterfly valve can be monitored via the feedback switches of 1061. Moreover, the actuator can be used as modulating control actuator by the addition of Bürkert’s range of Side Control positioners 8791/8792/8793.

    • Modular program for mounting of quarter turn valves such as ball valves and butterfly valves
    • NAMUR and ISO 5211 interfaces
    • Position feedback with Type 1061 possible (also for Ex applications)
    • SideControl Positioner ready - Type 8791/8792/8793
    • ATEX 2014/34/EU

    For selecting the correct product please refer to the technical data, images and notes for proper use according to the data sheet.
