Rotary actuators Series ARP
Model: “Rack & Pinion”
Sizes: 1, 3, 5, 10, 12, 20, 35, 55, 70, 100, 150, 250, 400
Rotational angles: 90°
Sizes: 1, 3, 5, 10, 12, 20, 35, 55, 70, 100, 150, 250, 400

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.

Cylinders Series 40K
Double acting, cushioned, magnetic
Ø 160 - 200 - 250 - 320 mm
Series 40K cylinders comply with the ISO 15552 standard and can be assembled with the entire range of standard accessories.
A permanent magnet on the piston of these cylinders is able to send, through proximity switches mounted on the cylinder sliding axis, electrical signals to indicate its position.This series is normally equipped with end-stroke cushioning which can be adjusted through a screw on the end block.
Cylinders with integrated guide Series QCTF – QCBF
Double-acting, magnetic, with double bearings and flanges
Ø 20, 25, 32, 40 mm
These cylinders have been designed to be used in applications where space is limited.
Regarding the bearings, the Slide Units are available in two versions, one with double sintered bronze bushes (Mod. QCTF) and the other with double linear ball bearings (Mod. QCBF).
The QCTF version would normally be selected when the side loads applied to the slide unit are high. Mod. QCBF is suitable for fast cycles (less side load) and higher precision.
The end cushioning is available in three different variants:
- Fixed mechanical cushion (standard);
- With two shock absorbers located on the body;
- With one shock absorber located central on the rear flange.
Series 32 compact cylinders, Tandem and Multi-position versions
Double-acting, magnetic
ø 25, 40, 63, 100 mm
Thanks to their great compactness Series 32 cylinders, Tandem and Multi-position, are suitable to be installed within confined spaces and can be used with the same mounting elements of other standard cylinders ISO15552.
The Tandem version enables to obtain up to 2 times the thrust force of a normal cylinder (standard traction force), while the Multi-position version can obtain up to three positions with one cylinder only.
Short-stroke cylinders Series QP – QPR
Series QP: single and double-acting, magnetic
Series QPR: double-acting magnetic, non-rotating
Ø 12, 16, 20, 25, 32, 40, 50, 63, 80, 100 mm
Series QP - QPR cylinders are available in 10 bore sizes, from Ø 12 to Ø 100.
Their compact dimension allows the installation in small spaces.
Because of their particular construction, they can be mounted by means of feet or trunnion.
The guides are manufactured in the external profile parallel to the sliding axis on three sides.
These are used to locate the switches that sense the piston position.
The non rotating guides make the QPR suitable for supply operations and for handling equipment.
Stainless steel cylinders Series 97
Single- and double-acting, cushioned, magnetic.
Ø 32, 40, 50, 63 mm
Series 97 stainless steel cylinders can be used in critical applications where a high level of corrosion resistance is required (for example: off-shore, naval, food industries).
These cylinders are normally equipped with end-stroke cushioning which can be adjusted through a screw on the end block.
In order to quieten the impact of the piston on the end block, these cylinders are also equipped with mechanical cushioning.
