Product Selection

< D20 / D22

Compact digital positioner

PMV D20/D22 is a compact digital positioner that suits both linear and rotary actuators. Its modular and flexible design allows mounting according to both the standards VDI/VDE 3845 for rotary and VDI/VDE 3847 for linear actuators with integrated tubing.

Further on, PMV D20/D22 offers feedback capability with optional plug in switches, HART communication and auto calibration for simple and trouble free commissioning.

The explosion proof version is available both in stainless steel and aluminium for single acting operation.
