Series ARP

Model: "Rack & Pinion"
Sizes: 1, 3, 5, 10, 12, 20, 35, 55, 70, 100, 150, 250, 400
Rotational angles: 90°
Series ARP rotary actuators have been designed to meet the high demands by the process industry, where they predominantly are used for controlling the opening and closing process valves whereas ball valves and butterfly valves are the most common types.

The actuators exist in thirteen different sizes in order to cover a wide range of applications. Through adjusting screws located on the end caps it is possible to mechanically adjust the opening/closing angle by ±5°.
All Series ARP rotary actuators are ATEX certified, the air connections are realized in accordance with Namur VDI/VDE 3845 drilling, while the interface drilling of the process valve is in accordance with ISO 5211 standard.
