    Features of the TBNS Series stainless steel pneumatic actuator

    ◆ ASTM316L、316、304 stainless steel pneumatic actuator with electro-polish finish offer excellent resistance to most corrosive chemicals as well as industrial atmospheres.

    ◆ Dual piston rack and pinion design for compact construction, symmetric mounting position, high-cycle life and fast operation, reverse rotation can be accomplished in the field by simply inverting the pistons.
    Multiple bearings and guides on racks and pistons, low friction, high cycle life and prevent shaft blowout.

    ◆ Modular preloaded spring cartridge design, with coated spring for simple versatile range, greater safely and corrosion resistance, longer cycle life.

    ◆ Fully machined teeth on piston and pinion for accurate low backlash rack and pinion engagement, maximum efficiency.
    The two independent external travel stop adjustment bolts can adjust ±5°at both open and close directions easily and precisely.
    Stainless steel fasteners for long term corrosion resistance.

    ◆ Full conformance to the latest specifications:ISO5211,DIN3337 and Namur or product interchangeability and easy mounting of solenoids, limit switches and other accessories.

    Sizing: Spring Return Actuators
    The suggested safety factor for double acting actuators under normal working conditions is 20%-30%.
    Example:
    The torque needed by valve=100N.m
    The torque considered safety factor
    (1+30%)=130N.m Air Supply=5Bar
    According to the above table, we can choose the minimum model is TBNS-105DA.

    Sizing: Spring Return Actuators

    The suggested safety factor for spring return actuator under normal working conditions is 30-50%
    Example：
    The torque needed by valve=80N.m
    The torque consider safety factor ( 1+30%)=104 N.mAir Supply=5Bar
    According to the table of spring return actuators’ output, we find output torque of TBNS140 K7 is:
    Air stroke 0°=308N.m
    Air stroke 90°=247N.m
    Spring stroke 90°=181N.m
    Spring stroke 0°=120N.m
    All the output torque is larger than we needed.
    Attention:
    During the restoration, the spring return actuators’ output torque will not be affected by the inputing air from the port B. On the contrary, it will help the restoration of springs.

    Operating Conditions

    1. Operating media Dry or lubricated air, the non-corrosive gases or oil.
    2. Air supply pressure Double acting: 2~8 Bar; Spring return: 2~ 8 Bar
    3. Operating temperature Standard:-20℃~+80℃      Low temperature:-40C~+80℃      High temperature:-20℃~+150℃
    4. Travel adjustment Have adjustment range of ±4°for the rotation at 90°
    5. Lubrication Under normal operating condition, need not accrete lubricant
    6. Application Either indoor or outdoor
    7. Highest pressure The maximum input pressure is 10 Bar

    Note

    Make sure that the torque necessary to operate the valve is compatible with the actuator torque (it depens on both actuator type and air supply). Please note that the requested torque depends not only on the valve, but on the working conditions and the safety margins of the plant in question, too.
