China TBNⅡ Series Rack and Pinion Pneumatic Actuator Suppliers & Factory for Quarter-Turn Valve Applications

The TBNⅡ series rack and pinion pneumatic actuator, manufactured in China, operates using compressed air to facilitate linear motion. This motion drives the gear transmission of the output shaft, resulting in precise angular stroke output. Available in both double-acting and single-acting configurations, this versatile pneumatic actuator is ideal for controlling and adjusting quarter-turn valves such as ball valves, butterfly valves, and plug valves. As a leading supplier and factory of pneumatic actuators, we ensure quality and reliability for various rotary applications. Choose our TBNⅡ series for effective and efficient performance in your industrial operations

    Product Detail

    TBN series rack and pinion pneumatic actuator69m1
    • 1. Extruded aluminium body: Hard anodized internally and externally for corrosion protection. Honed cylinder surface guarantees a longer life and lower coefficient of friction.
    • 2. Dual piston rack and pinion design: Delivers a compact construction, symmetric mounting position, high cycle life, and fast operation. Reverse rotation can be easily accomplished in the field by simply inverting the pistons.
    • 3. One-piece gear output shaft: Nickel-plated for a long service life. Custom 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 an easy and precise adjustment of +/-5° in both open and close directions for accurate valve alignment.
    • 6. High-quality bearings & 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 excellent corrosion resistance.
    • 8. Stainless steel fasteners: Internal and external fasteners provide long-term resistance to corrosion.
    • 9. Full Conformance: Fully complies with ISO 5211, DIN 3337, and VDI/VDE 3845 NAMUR specifications for product interchangeability and easy mounting of solenoids, limit switches, and other accessories.

    Operating Principles

    Dual Action

    • 7xm1
      Step 1

      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.

    • 8qt4
      Step 2

      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)

    • 9txn
      Step 1

      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.

    • 10vvk
      Step 2

      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)

    • 11q1c
      Step 1

      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.

    • 12u8w
      Step 2

      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 main body features of the TBN series pneumatic actuator?

    The TBN series features an extruded aluminium body with internal and external hard anodized corrosion protection. The honed cylinder surface reduces the coefficient of friction and extends the service life.

    How does the travel stop adjustment work on these actuators?

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

    Are the TBN actuators compatible with standard industry accessories?

    Yes. The actuators fully conform to ISO 5211, DIN 3337, and VDI/VDE 3845 NAMUR specifications. This ensures complete product interchangeability and allows easy mounting of solenoids, limit switches, and other standard accessories.

    What is the difference between Spring Return FC and Spring Return FO configurations?

    Spring Return FC (Fail Close) uses spring force to automatically close the valve clockwise upon air or power loss. Spring Return FO (Fail Open) uses spring force to automatically open the valve counter-clockwise when there is an air or power disruption.

    Can the rotation direction of the actuator be changed in the field?

    Yes. Due to the symmetric dual piston rack and pinion design, reverse rotation can be easily accomplished in the field by simply inverting the pistons.
