The positioner is used to move and control pneumatic actuators. The positioner works
electropneumatically, using compressed air as auxiliary power. The positioner is used to
control valves, for example, with:
● Linear actuator
● Part-turn actuator VDI/VDE 3845
Various add-on extensions are available for linear actuators:
● IEC 60534-6-1 (NAMUR)
● Integrated mounting ARCA, except with flameproof versions
● Integrated addition to SAMSON in non-flameproof aluminum enclosure
① Pressure gauge block, single-acting
② Valve
③ Yoke / actuator yoke
④ Single-acting positioner in non-flameproof aluminum enclosure
⑤ Actuator
