9. Distinguished Characteristics:
(1)Patented spring module: Output torque adjustable, Springs
replaceable fit different type of valve's torque.
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
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
The shaft driven accessory interface conforms to NUMAR and
is identical on all DFA Series, allowing standardization of
accessory mounting hardware and installation practices.
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.
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
Replaceable Bearings protect sliding and rotation
components, with suitability for either dry or lubricated
(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.
