Single-acting actuators are used as an example of a SR-series pneumatic actuator. In a spring-reset application, the output torque is obtained during two different operations. Depending on the travel position, each operation produces two different torque values. The output torque of the spring return actuator is multiplied by the force (air pressure or spring force) multiplied by the force arm. The output torque is obtained by the air pressure entering the middle compression spring, called "air stroke output torque" In this case, the air supply pressure forces the piston from 0 ° to 90 ° position. As the spring compresses the reaction force, the torque gradually decreases from the starting point to the second condition: the output torque is the spring recovery when the cavity is lost Force acting on the piston, known as the "spring stroke output torque" In this case, the output torque gradually decreases from 90 degrees to 0 degrees due to the elongation of the spring. As described above, the single acting actuator is based on two Kind of condition produced under a balanced torque on the basis of the design.
