for the process industry

DFPB semi-rotary actuator

Sturdy rack & pinion drive – designed for harsh ambient conditions in the process industry

The benefits to you:

  • Compact design
  • One housing for single and double-acting drives
  • Constant torque characteristics
  • Long service life: low wear due to innovative, pressure-dependent lip seal
  • Clockwise and anti-clockwise operation due to process valve connections on both sides as per ISO 5211
  • Extremely fine torque gradation: this ensures optimum adaptation to the process valve
