KSB Actair Double-acting Pneumatic Actuator

The KSB Actair is a Double-acting Pneumatic Actuator to be mounted on quarter-turn Valves (Butterfly or Ball Valves). The KSB Actair has a control pressure up to 8 bar and can be mounted on various types of valve stem ends (square end, flat end or key). It has force transmission via rack-and-pinion, and scotch-yoke or patented Amri yoke kinematics provides output torques of up to 16000 Nm which are ideal for actuating quarter-turn valves. The KSB Actair is equipped with a visual position indicator and adjustable travel stops for open/closed position as standard. Manual override can be provided on request.

For automated valve actuation, ACTAIR can be combined with AMTROBOX, AMTRONIC, SMARTRONIC or any other control unit with VDI/VDE 3845 interface.
