ACTAIR EVO

Double-acting pneumatic actuator for mounting on quarter-turn valves with ISO 5211 compliant shaft ends (butterfly valves or ball valves). Actuator flange to ISO 5211. Control pressure up to 8 bar. Force transmission via scotch-yoke kinematics provides output torques of up to 8000 Nm which are ideal for actuating quarter-turn valves. Equipped with a visual position indicator and, depending on the actuator size, adjustable travel stops for open/closed position or closed position as standard. Optional separate or integrated manual override. Suitable for mounting control unit type series AMTROBOX, AMTRONIC U, SMARTRONIC U or any other device with an interface to VDI/VDE 3845.

Benefits

Actuator for all types of quarter-turn valves (butterfly valves, ball/plug valves)
Position indicator and one or several adjustable travel stops
Unlike rack-and-pinion kinematics, the actuator’s scotch yoke mechanism delivers peak torque at both valve opening and closure.
