TBNS Series Stainless Steel Pneumatic Actuator

TBNS Series Stainless Steel Pneumatic Actuator

Model: TBNS052-TBNS400DA/SR, 16 models, material 304ss or 316ss, output torque 20N.m ~8120N.m at 5bar air supply, ISO5211/DIN3337 to match valve connection, Namur interface for the accessories, ±5°adjustment, with ATEX certification.

TBNS Series stainless steel pneumatic actuator is powered by compressed air, through the linear motion of the piston rack drives the gear output shaft, to angle stroke output pneumatic actuators. A double action and single action type, widely applicable to ball valve, butterfly valve switch, plug valve isometric stroke of the valve and adjusting, can also be used in other rotary occasions, is to realize the ideal device for industrial pipeline automation control.

    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.

    Operating Principle and Out Torque

    Double action
    1

    CCW

    Air to Port A forces the pistons outwards, causing the pinion to turn counter clock wise while the air isbeing exhausted from Port B.

    2

    CW

    Air to Port B forces the pistons inwards, causing the pinion to turn clock wise while the air is being exhausted from Port A.

    Single action
    3

    CCW

    Air to Port A forces the pistons outwards, causing the springs to compress, The pinion turns counter-clockwise while air is being exhausted from Port B.

    4

    CW

    Loss of air pressure, the stored energy in the springs forces the pistons inwards, the pinion turns clock wise while air is being exhausted from Port A.

    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.
