DYNACTAIR EVO

DYNACTAIR EVO

Single-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 4000 Nm which are ideal for actuating quarter-turn valves. Reset to fail-safe position in case of control air failure is effected by means of spring assemblies. Equipped with a visual position indicator and, depending on the actuator size, adjustable travel stops for closed position or open/closed position as standard. Optional separate or integrated emergency 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.
