- Combination with top control positioner Type 8691/⅔/4 possible Ideally suited for hygienic applications 100 % maintenance-free (welded stainless steel housing) Streamline design Standardised interface acc. to ISO 5211 The pneumatic actuator Type 2053 enables the automated actuation of ball and butterfly valves. The linear stroke movement of the actuator piston is deflected into a 90° rotary movement of the drive shaft. The interface on the armature is designed according to ISO 5211. In addition, the rotary actuator can be combined with the 8691/⅔/4 series position feedback sensors. The single-acting actuators are returned to the initial position by spring force, while double-acting actuators are returned by compressed air. The welded construction of the stainless steel housing ensures the actuator is 100 % maintenance-free. Overall, the actuator is available in three different sizes: P0 - P1 - P2. All three sizes have an extremely high torque in the closing area despite their compact design. The air consumption per stroke cycle is very low due to the low cylinder volume. This offers a remarkable energy saving potential. Product variants described in the data sheet may differ from the product presentation and description.

Product operation 6.1. Functional overview Function Description
- The linear lifting motion of the drive piston is redirected in a 90° rotational movement of the drive shaft. The return to the initial position of the single-acting actuators is caused by spring force. For the double-acting actuators, the movement in both directions is caused by compressed air.
