Quarter turn actuator


General DPN

Festo has announced the Copar drive (compact pneumatic rotary drive) Type DRD (double-acting) and DRE (single-acting), an optimized 90° rotary actuator. Its main features are the Namur interface and the interface for assembly of a process valve. The interface to VDI/VDE 3845, for assembly of a valve on the side of the drive, permits direct mounting of a Namur valve and facilitates the mounting of limit switches, limit switch boxes, positioners and customary actuators.

The interface for the process valve to DIN/ISO 5211 in many cases permits direct mounting on a butterfly valve or a ball valve. Salt-water resistant aluminum is used for the cylinders. The DRE/DRD actuator comes with or without end position adjustments and sensing.
