The 2051 pneumatic rotary drives are low maintenance single or double-acting pneumatic linear piston actuators where 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 SO 5211 mechanical interface and the status of ball or butterfly valve can be monitor data control system through a range of rugged feedback switches.
The drives can also be used as modulating control actuators by the addition of Bürkert’s range of Side Control positioners.
Features- Modular program for mounting of quarter turn valves such as ball valves and butterfly valves
- NAMUR and ISO 5211 interfaces
- Position feedback (including Ex-Versions )
- SideControl Positioner ready
