KSB - Quarter Turn Double Acting Pneumatic Actuator
KSB - Quarter Turn Double Acting Pneumatic Actuator

Double-acting pneumatic actuator for mounting on quarter-turn valves (butterfly valves or ball valves). Top flange to ISO 5211. Control pressure up to 8 bar. Can be mounted on various types of valve stem ends (square end, flat end or key). Force transmission via rack-and-pinion, scotch-yoke or patented Amri yoke kinematics provides output torques of up to 16000 Nm which are ideal for actuating quarter-turn valves. 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.
