Product Description

stainless steel neumatic actuator Pvc Pneumatic Ball Valve for valve gearboxes

What is a pneumatic actuator
A pneumatic actuator is a device that converts energy in the form of compressed air into mechanical motion. Pneumatic actuators are commonly used in industrial environments to control valves, open and close doors, and move objects.
There are two main types of pneumatic actuators: linear and rotary. Linear actuators move in a straight line, while rotary actuators move in a circular motion.
Linear actuators are typically used in applications that require precise motion, such as in valve control. Rotary actuators are typically used in applications that require high torque, such as opening and closing doors.

Model Selection and Data
Selection of executing agency
When selecting an actuator, a safety value should be added to the specified valve torque, such as a 25% safety value for steam or non-lubricating liquid media, three safety values for non-lubricating paste or liquid media, 40% safety value for non-lubricating dry gas media, and 60% safety value for non-lubricating particles or powders transmitted through gas; 20% safety value for clean and low friction lubricating media (the above are the theoretical safety values recommended by our company for reference only)
Example of selecting a DR double-acting actuator
When controlling the ball valve, the torque is 200NM, the supply pressure is a bar, and the medium is non-lubricating steam. Considering safety factors, a 25% safety value equal to 250NM should be added. You can add a supply pressure of bar to the double-acting output torque table, then search for equivalent approximate torque data in the vertical line, select 306 8NM, and then search left for the model in the line, and choose AT125DR. (Figure 1)
Example of selecting SC single-acting actuator
When controlling the butterfly valve, the torque is 100NM, and the supply pressure of the non-lubricating dry gas medium is 4 bar. Considering safety factors, you should add a 40% safety value equal to 140NM. Search for a torque of approximately 142NM in the spring reset terminal of the single action output torque table, and then find the terminal torque of 156NM to the left in this row (for a supply pressure of 4 bar). You must be the relative balance between the supply pressure torque and the spring reset torque; Then, search to the left for the model and number of springs online, and select AT 140SC and eight springs.
