Adapts SW11 actuator drives to SW9 process valve shafts. Sintered stainless steel construction yields CRC 2 rating and VDMA24364 zone III purity.
The Festo 8082117 (model DARQ-R-A-S11-S9-11) is a precision-engineered reducing sleeve designed for reliable drive adaptation between rotary actuators and process valves. It features an SW11 external octagon drive and an SW9 internal square socket. Fabricated from highly durable sintered stainless steel, it is built to withstand rigorous industrial environments with a Corrosion Resistance Class (CRC) of 2. Furthermore, its VDMA24364 zone III compliance ensures it is free from paint-wetting impairment substances (PWIS), making it suitable for automotive and high-purity cleanroom applications.

Utilized to mate a Festo rotary actuator with an 11mm drive output to a process ball valve or butterfly valve requiring a 9mm square input.
Eliminates physical misalignment and drive incompatibility between different sized shafts, allowing direct torque transmission without custom machining.
Deployed in chemical processing or water treatment facilities where the pneumatic actuator linkage is exposed to moderate moisture and corrosive agents.
The sintered stainless steel construction and CRC 2 rating ensure the coupling sleeve will not rust or fail prematurely in moderately corrosive environments, preventing linkage lock-up.
Used in automotive painting or coating lines where process valves and actuators must be strictly free of silicone or paint-wetting impairment substances (PWIS).
Meets strict VDMA24364 zone III standards to ensure that no contaminants interfere with surface finishing processes, maintaining full compliance in clean spray environments.
