The 2052 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 ISO 5211 mechanical interface and the status of ball or butterfly valve can be monitored at a 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. The drive is both internally and externally Cataphoresis and Rilsan coated, which makes it highly resistant to corrosion and maintenance free.
Features- Modular program for mounting of quarter turn valves such as ball valves and butterfly valves
