Datasheets

Double acting pneumatic actuator with 0–180° rotation, designed for three-way valves and any application needing a half-turn stroke. It delivers 39.5 Nm at 6 bar.

The body is hard-anodised extruded aluminium, and travel can be set both with the internal cam and with the screws on the end caps, so the valve stops exactly in the required positions.
