China TBNⅡ Series Rack and Pinion Pneumatic Actuator - Trusted Suppliers & Quality Factory Product

The TBNⅡ series rack and pinion pneumatic actuator is an innovative solution designed and manufactured by our China factory. Utilizing compressed air, this actuator converts linear motion of the piston rack into gear transmission for the output shaft, delivering precise angular strokes. Available in both double-acting and single-acting types, it is extensively employed for operating quarter-turn valves, including ball valves, butterfly valves, and plug valves. As a leading supplier in the industry, we also ensure that our products can be adapted for various rotary applications, making them essential for diverse automation needs

    Product Detail

    TBN series rack and pinion pneumatic actuator69m1
    • 1. Extruded aluminium body: Honed cylinder surface with both internal and external hard anodized corrosion protection for longer life and lower coefficient of friction.
    • 2. Dual piston rack and pinion design: Compact construction, symmetric mounting position, high cycle life and fast operation. Reverse rotation can be accomplished in the field by simply inverting the pistons.
    • 3. One-piece gear output shaft: Nickel plated for long service life. Customized sizes and stainless steel material are available as options.
    • 4. Die-cast aluminum alloy end caps: Epoxy coated with high anti-corrosion performance. Various colors or PTFE coating can be customized.
    • 5. Two independent external travel stop adjustments: Permits easy and precise adjustment of +/-5° in both directions (open and close positions) for accurate valve alignment.
    • 6. High quality bearings and seals: Selected for low friction, high cycle life, and a wide operating temperature range.
    • 7. Modular preloaded spring cartridge design: Coated springs provide a simple versatile range, greater safety, and high corrosion resistance.
    • 8. Stainless steel fasteners: Both internal and external fasteners ensure long-term corrosion resistance.
    • 9. Standards Conformance: Fully conforms to the latest ISO 5211, DIN 3337, and VDI/VDE 3845 NAMUR specifications for product interchangeability and easy mounting of solenoids, limit switches, and other accessories.

    Frequently Asked Questions

    What materials are used for the TBN series pneumatic actuator body and end caps?

    The TBN series features an extruded aluminium body with internal and external hard anodized corrosion protection. The end caps are constructed from die-cast aluminum alloy with a protective epoxy coating for high anti-corrosion performance.

    How does the travel stop adjustment work on these actuators?

    The actuator is designed with two independent external travel stop adjustments. This setup allows for easy and precise adjustments of +/-5° in both open and close directions, ensuring accurate valve alignment.

    Can the rotation direction of the TBN series pneumatic actuator be reversed?

    Yes, the rotation direction can be easily reversed directly in the field. Due to the dual piston rack and pinion design, reverse rotation is achieved simply by inverting the pistons inside the cylinder.

    What standards do the TBN series pneumatic actuators comply with?

    The actuators fully conform to the latest ISO 5211, DIN 3337, and VDI/VDE 3845 NAMUR specifications. This ensures full product interchangeability and simplifies the mounting of solenoids, limit switches, and other accessories.

    What is the difference between Spring Return FC (Fail Close) and FO (Fail Open) configurations?

    In the FC (Fail Close) configuration, spring rebound forces the pistons inward to close the valve upon air or power disruption. In the FO (Fail Open) configuration, the spring rebound forces the pistons inward to open the valve when a power or air disruption occurs.
