AUMA PART-TURN ACTUATORS
Part-turn actuators (aka: quarter-turn actuators) are designed for 90-degree rotary motion. These actuators are commonly used for controlling valves, such as ball valves and butterfly valves, that require only a limited amount of rotation to open or close.
Part-turn actuators are an essential component of automated valve systems, allowing for precise and efficient control of valve position. AUMA is a leading manufacturer of electric part-turn actuators, offering a range of motorized solutions that are reliable, durable, and easy to install. An electric part-turn actuator from AUMA can be used to automate a wide range of industrial valves, including ball valves, butterfly valves, and plug valves.
AUMA part-turn actuators are known for their high torque, compact design, and reliability, making them suitable for a wide range of industrial applications. They are available in different sizes, materials, and control options to meet the specific requirements of each application.
With part-turn actuators of AUMA, you can expect precise and efficient control of your quarter-turn valves.
AUMA SQ & SQR types electric part-turn actuators
In compliance with EN ISO 5211, electric part-turn actuators transmit torque to the valve for a rotation of one revolution or less. They do not have to be capable of withstanding axial thrust.
Part-turn valves – such as butterfl y valves and ball valves – are often designed in multi-turn version. AUMA SQ part-turn actuators are equipped with internal end stops to allow precise approaching of end positions during handwheel operation.
AUMA SQ part-turn actuators for open-close duty
The open-close duty of an electrical part-turn actuator refers to its ability to alternately open and close a valve or other device by rotating through a limited angle, usually 90 degrees or less. Part-turn actuators are used for controlling valves that require only a small amount of rotation to switch between open and closed positions, such as ball valves and butterfly valves. The open-close duty cycle of a part-turn actuator will depend on the specific application and requirements, such as the speed and torque needed to perform the open-close cycle. Part-turn actuators with open-close duty are widely used in control systems, especially in industries such as water treatment, HVAC, oil and gas, and power generation.

AUMA SQR part-turn actuators for modulating duty
The modulating duty of an electrical part-turn actuator refers to its ability to accurately control the position of a valve by continuously adjusting the valve’s opening degree in response to a changing control signal. AUMA part-turn actuators are commonly used in heating, ventilation, and air conditioning (HVAC) systems and industrial process control applications where precise regulation of fluid flow is required. The modulating duty is typically expressed as a percentage of the full-turn range, and it can be affected by factors such as the actuator’s torque output, the valve’s stiffness, and the control system’s response time.
The following data applies to part-turn actuators with 3-phase motors, operated in type of duty S4 – 25 %/class C in compliance with EN 15714-2.
