Pneumatic actuators TORK are powerful, reliable, and compact units with fast or slow 90° rotation. They are manufactured in both single-acting and double-acting versions. In addition to the standard manufacturing process, actuators can also be produced with ± 10% stroke adjustment, 180° rotation, and three closing positions (closed, open, half-open). Suitable for use with ball valves, butterfly valves, threads, and dampers.

TORK pneumatic actuators now meet the quality standards according to the SIL 3 scale.

The International Electrotechnical Commission (IEC) has issued the standard IEC 61108, which defines safety requirements. Both the device and the system must meet all categories of requirements to achieve SIL certification. The SIL 3 level allows for the possibility of a dangerous product error once every 1,140 years.
