This pneumatic quarter turn actuator works according to the double piston rack and pinion principle, and is available as a double acting (ADA) or single acting (ASR) version. It is ideal for mounting on butterfly valves and ball valves with standardised interfaces in accordance with ISO 5211 or DIN 3337 (F03-F25). To attach accessories, defined mounting facilities are also available in accordance with VDI/VDE 3845 and NAMUR (control air connector).



  • Version A: The aluminium housing is hard-anodised on both the insideиand the outside. This treatment means that the surface will be extremelyиabrasion-resistant (which leads to reduced wear of the adjacent, dynamic components). In addition, this means that a good level of resistance against external environmental influences (e.g. industrial atmosphere) can be achieved. The end caps are provided with an epoxy
    coating (80-90 µm).
  • Version F: The aluminium housing and the end caps are provided with a high-quality epoxy coating (80-90 µm). Shaft and screws are made of stainless steel. This achieves an excellent level of corrosion protection. This type of coating has been tried and tested in the offshore sector and in buildings that have permanent condensation and severe air pollution, among others.
    Optical position indicator
    The multifunction indicator is used as an optical position indicator. It can also be used to operate mechanical or inductive switches for the electronic position feedback.
    Setting end positions
    The setting range is ±5° (85° to 95°). This adjustment facility has been designed to be extremely easy to operate and is implemented using a precise cam system. The settings can be implemented without removing the actuator. By using a stroke limiter (optional), the end positions can be set variably between 0° and 90°.
