The KINETROL single-acting part-turn actuators are the best choice for safety-related applications on the market.

The unique design of the spring-loaded unit with a spiral spring ensures the lowest torque loss in the course of a spring stroke compared to other pneumatic quarter-turn actuators. The deviation is about 17-20% from the beginning to the end position. With KINETROL rotary actuators, the torque is available in both directions of rotation.

The springs are loaded only to a small part of the maximum allowable stress. Therefore, an extremely long life-time and no fatigue is the result. Another advantage is the installation of the springs in a separate enclosure with IP 65 protection.

The KINETROL Spring Units for single-acting actuators are available in Kinetrol standard and DIN versions.
