Single-Spring Actuator
AoTu-D2 Series pneumatic diaphragm actuators are designed to perform long strokes, usually covered by cylinder-operated actuators.
They are manufactured by OTEKER to suitably operate control valves both for throttling and on-off service.
The thrust is supplied by a rubber, air-Ioaded diaphragm and, in the opposite direction, by an helical spring.
Standard model can be delivered either as a direct-acting actuator (model 1-D21) or, replacing a minimal number of parts, as a reverse-acting actuator (model 1-D22).
Two actuator sizes are available: D46 and D63.
Special version double effect spring return D63 size is available for more critical applications.
