    Pneumatic Power Module with Extended Travel Stops,

    Spring exchangeable,

    Spring Module with Patented Adjustable Output Torque and

    Integral Override gear operator,

    Hydraulic Power Module or Override for Hydaulic Actuators


    Pneumatic Power Modul,

    Spring Module with Patented Adjustable Output Torque,

    Integral Override Hydraulic Cylinder

    9. Distinguished Characteristics:

    (1)Patented spring module: Output torque adjustable, Springs

    replaceable fit different type of valve's torque.

    (2)Corrosion Resistan:

    The DFA series actuators incorporate over three stages of

    internal and external coatings to resist severe weather,

    chemical and petroleum environments. The inner surface of

    cylinder is coated by PTFE, enhanced corrosion resistant and


    (3)Modular Design:

    DFA series actuators have available, field-serviceable

    drive, power, spring and override modules, the modules are

    removable, serviceable and interchangeable when mounted to

    the valve. Modules are available for separate purchase to

    reduce spare parts inventory.

    (4)Safe Spring Module:

    To ensure the safety of personnel during installlation and

    maintenance, the spring module has been designed so that it

    can only be removed from the power module with the spring in

    the fully extended position. This prevents accidental

    release of the spring force, protecting personnel from

    injury and the actuator from accidental damage.

    (5)Water Ingress Protected:

    O-rings are fitted on bodies, caps and so on, this ensure

    water ingress protected.

    (6)ISO Valve Mounting:

    The DFA Series actuators interface meets ISO standard, and

    meets the dimensional Requirements of ISO defined for each

    torque range.


    The shaft driven accessory interface conforms to NUMAR and

    is identical on all DFA Series, allowing standardization of

    accessory mounting hardware and installation practices.

    (8)Wear Resistant:

    The guide rod and piston rod have an advanced surface

    treatment, which combined with

    Self-lubricating bearings, provides superior wear resistance

    and extends the life of all sliding components.

    (9)High Efficiency:

    The piston rod and guide block connection superior surface

    finishes and self-lubricating bearings maximize input energy

    transfer directly to the valve stem, efficiency is further

    enhanced by the tension-loaded spring, minimizing radial

    loads on the piston rod.

    (10)Precompressed spring unit:

    Precompressed spring unit easy to exchange, to ensure safe


    (11)Replaceable Bearings:

    Replaceable Bearings protect sliding and rotation

    components, with suitability for either dry or lubricated

    working conditions.

    (12)Hydraulic Overrides for Spring Module:

    Inside hydraulic override cylinder module for spring-return

    models does not increase actuator length.

    (13)PTFE Guide Ring:

    Guide ring, made of PTFE, prevents metal to metal contact

    with the cylinder bore, protect the cylinder from being

    scratched by pistons.


    Roller used reduce the friction between the yoke arm and

    pin, minimizing the wear of yoke arm and pin.

    (15)80° -100° Traval Adjustment:

    Bi-Directional Travel Stops integral to the actuator, the

    stops allow 80° -100° Total travel adjustment.
