Page 3: Introduction
The A-Series 530 lb-in actuator is a quarter-turn industrial electric actuator. It features a compact, reliable design that mounts directly to Siemens resilient seat butterfly valves without the need for brackets and linkages. This unit provides up to 530 lb-in (60 Nm) torque, and is available in 24V and 120V, Two-Position (On/Off) and Modulating units all in NEMA 4X and IP65-rated housings. -
Page 4: Heater
Introduction Heater Heater The A-Series 530 lb-in actuator includes a factory-installed heater that prevents condensation from forming inside the actuator. Units with On/Off actuation use a Positive Temperature Coefficient (PTC) style heater which has a unique temperature – resistance characteristic. The heater self-regulates by increasing its electrical resistance relative to is temperature. -
Page 5: Mechanical Operation
Introduction Mechanical Operation Mechanical Operation Mechanically, the ratio of the gearing determines the output speed of the unit. The actuator utilizes high efficiency spur gears. Positioning is determined by an indicator/cam shaft, which is linked to the output shaft. In the declutched position, the manual override drives the output. -
Page 6: Storage
Storage CAUTION Actuators are not weatherproof unless they are properly installed on the valve or prepared for storage. Siemens cannot accept responsibility for deterioration caused on-site. ● Store units on a shelf or wooden pallet to protect against floor dampness. -
Page 7: Actuation
Actuation Manual Operation Actuation Manual Operation The A-Series 530 lb-in actuators have a declutchable, manual override system. To manually operate the actuators, push in the manual override button and rotate the declutchable lever counter-clockwise until it reaches the 12 o’clock position. Once the declutchable lever is in position, turn the handwheel until the valve reaches the required position. -

Page 18: Description Of Operation
A-Series 530 lb-in Servo Controller Description of Operation Description of Operation The Servo controller provides complete modulating control and monitoring of the 530 lb-in Electric Actuator. The basic function of the Servo is to position the Actuator in response to a command signal from a process controller. The process controller contains a desired process setpoint entered by the user, and continually monitors the process variable (such as flow rate, tank level, etc.) through some type of sensor. -
