    Product Feature

    BP Series Actuator Features
    1 Totally Enclosed Housing Design

    Totally enclosed weatherproof centre body fabricated in carbon steel or Centre body has been designed totally enclosed, weatherproof housing fabricated in carbon steel or welding material provide an excellent strength.

    2 Standard Mounting Flange

    The mounting flange accord with the ISO5211 standard, accessories mounting size accord with NAMUR VDI/VDE 3845, which is convenient for mounting accessories such as Limit Switch box, Positioner and so on.

    3 Wear Resistant

    The guide rod and piston rod with advanced surface treatment combined with self-lubricating bearings, which provides superior wear resistance and extends the life of all sliding components.

    4 Water Ingress Protected

    Sealing gaskets are fitted in the joint between body, cap, pneumatic cylinder and so on, which prevent from water ingress.

    5 Corrosion Resistant

    BP series pneumatic actuators coated with over 3 layers of protective coating, which can meet the requirements of the petrochemical and coastal environment.

    6 Self-lubricating

    BP series pneumatic actuator has been designed to be completely self-lubricating, which ensure maximum wear resistance and long cycle life. No need of lubrication.

    7 Modular construction Design

    BP series pneumatic actuator has a efficient and interchangeable modular construction design, including centre body, pneumatic cylinder, spring cartridge, hydraulic cylinder, override modular and so on. Modular construction and stocking of components by THEOBORN facilitates quick delivery time.

    8 Safe Spring Module

    To ensure the safety of personnel during installation and maintenance, the spring cartridge module can be only removed from the axes of the pneumatic cylinder module, which avoids the damage to the working people and pneumatic devices.

    9 Manual Override

    Available with declutchable manual override and hydraulic manual override.

    10 Minimum Maintenance

    BP series pneumatic actuator is built to provide long and efficient service with minimum maintenance.

    Structure Feature

    1 Steel Guide Bar

    Hard chrome plated alloy steel guide bar provides optimal support of the transverse loads.

    2 Slider Block

    Aluminum bronze slider blocks and high frequency quenching steel shaft pin minimize contact stress and ensure high cycle life.

    3 Cylinder

    Electroless nickel plated and polished cylinder for corrosion resistance and minimal friction.

    4 Guide Ring

    Made from low friction, long-life compound material, to avoid the direct contact between metals, the maintenance and replacement are easy and convenient.

    5 Spring

    High strength alloy steel spring to maintain consistent torque output and promote high cycle life performance.

    6 Travel Adjustment

    Bi-directional travel stops allows 90°±5° travel adjustment, which make the valve be in the best position.

    Frequently Asked Questions (FAQ)

    What mechanism design do BP series actuators use?

    BP series actuators adopt the classical scotch yoke mechanism design. This design allows them to output maximum torque at both ends of the stroke, making them highly efficient for 90° rotation valves.

    What is the operating pressure range for pneumatic and hydraulic models?

    For pneumatic actuators, the operating pressure ranges from 3 to 10 Bar. For hydraulic actuators, the operating pressure ranges from 50 to 250 Bar.

    What ambient temperatures can the BP series actuators withstand?

    They are available in three variants: Standard actuator (-20°C to +80°C), Low temperature actuator (-40°C to +80°C), and High temperature actuator (-20°C to +120°C).

    Are these actuators suitable for corrosive environments?

    Yes, BP series pneumatic actuators are coated with over 3 layers of protective coating, designed to meet the harsh requirements of petrochemical and coastal environments.

    What standards do the mounting flanges and accessories comply with?

    The mounting flanges comply with the ISO5211 standard, and accessory mounting sizes comply with the NAMUR VDI/VDE 3845 standard for easy integration of limit switch boxes, positioners, and other components.

    Do BP series actuators require regular lubrication?

    No, BP series pneumatic actuators are designed to be completely self-lubricating. This ensures maximum wear resistance, a long cycle life, and minimum maintenance without the need for manual lubrication.
