Dual Action Operation
01 Air from Port A forces the pistons outwards, causing the springs to compress, the pinion turns counter-clockwise to open the valve while air is being exhausted from Port B.
02 Air from Port B forces the pistons inwards causing the springs to compress, the pinion turns clockwise to close the valve while air is being exhausted from Port A.
Spring Return (FC) Operation
01 Air from Port A forces the pistons outwards causing the springs to compress, the pinion turns counter-clockwise to open the valve while air is being exhausted from Port B.
02 In case of air or power disruption, the rebound of springs forces the pistons inwards, the pinion turns clockwise to close the valve while air is being exhausted from Port A. Air from Port B can accelerate the close of the valve.
Spring Return (FO) Operation
01 Air from Port A forces the pistons outwards causing the springs to compress, the pinion turns clockwise to close the valve while air is being exhausted from Port B.
02 In case of air or power disruption, the rebound of springs forces the pistons inwards, the pinion turns counter-clockwise to open the valve while air is being exhausted from Port A. Air from Port B can accelerate the open of the valve.
Frequently Asked Questions (FAQ)
What are the key design features of the TBN series pneumatic actuator body?
The actuator features an extruded aluminium body with both internal and external hard anodized corrosion protection. The honed cylinder surface provides a longer life and a lower coefficient of friction.
How does the travel stop adjustment work on this rack and pinion pneumatic actuator?
It features two independent external travel stop adjustments. This design permits an easy and precise adjustment of +/-5° in both directions (open and close positions) for accurate valve alignment.
Which international standards does the TBN series pneumatic actuator conform to?
The actuator fully conforms to the latest specifications of ISO 5211, DIN 3337, and VDI/VDE 3845 NAMUR. This ensures excellent product interchangeability and easy mounting of solenoids, limit switches, and other accessories.
What is the difference between Spring Return FC (Fail Close) and FO (Fail Open) operations?
In Spring Return FC operation, air from Port A opens the valve, and springs force the pistons inward to close the valve during air disruption. In Spring Return FO operation, air from Port A closes the valve, and springs force the pistons inward to open the valve when air is disrupted.
What materials are used for the end caps and output shaft?
The end caps are made of die-cast aluminum alloy coated with epoxy for high anti-corrosion performance. The output shaft is a one-piece gear made of nickel-plated alloy steel, with customizable sizes and stainless steel options available.
How can the rotation direction of the pistons be reversed in the field?
Due to the dual piston rack and pinion design with symmetric mounting positions, reverse rotation can be easily accomplished in the field by simply inverting the pistons.
