Operating Function and Direction of Rotation
Note:
1. For double acting actuator, the standard rotation is clockwise for closing and counterclockwise for opening. If the assembly direction of the piston is reversed, then the rotation will be counter clockwise for closing and clockwise for opening.
2. For single acting actuator, the standard is fail close type (FC), as shown above. If the assembly direction of the piston is reversed, then it will be fail open type (FO).
Frequently Asked Questions
What materials are used for the actuator cylinder and piston?
Both the cylinder (Part 1) and the piston (Part 12) are constructed from high-grade Aluminum Alloy and protected with an Anodized Oxygenation finish to ensure durability and corrosion resistance.
What is the standard rotation direction for a double acting actuator?
The standard rotation is clockwise (CW) for closing and counterclockwise (CCW) for opening. If your operation requires the opposite, the rotation can be reversed by changing the assembly direction of the piston.
What does FC and FO stand for in single acting actuators?
FC stands for "Fail Close", which is the standard setup where the spring action closes the valve upon loss of air pressure. FO stands for "Fail Open", achieved by reversing the piston assembly direction, where the springs open the valve when pressure is lost.
How are the internal springs protected against corrosion?
The springs (Part 21) are made of resilient Spring Steel and receive double-layer protection: an electrophoresis paint coat followed by a robust Epoxy outer coating to withstand harsh environments.
What air pressure ranges are supported by these actuators?
According to the torque tables, the actuators are rated for air supply pressures ranging from 2 bar up to 8 bar for double acting configurations, and 3 bar to 7 bar for single acting configurations.
Which standard connection sizes are available for the TBN series?
The TBN series supports standard ISO flange connections ranging from F03 up to F25 (depending on the model size), with air port thread sizes ranging from G1/8 to G1/2 to suit various pneumatic supply systems.
