FieldQ actuators
are suitable for use in SIL3 applications where a periodic
partial stroke test is performed. Where partial stroke
testing is not required the FieldQ actuators are suitable
for use in SIL2 applications.
|
Springs
FieldQ springs are designed and manufactured never to break
and are protected from corrosion using a Deltatone® coating.
Control Module
Control Modules
provide the flexibility to select the right functionality
for your application. This modular system provides the
possibility to upgrade to digital communications as well as
enable the fitment of a local manual control and a variety
of glands and quick connectors.
Pneumatic Module
The patented,
reliable diaphragm/poppet design offers a high air volume
capacity without the need for filtered air required by
conventional spool or solenoid valves. Most importantly
however it provides a reliable, long working life. A
breather function, standard on single acting versions
provides protection of the actuator spring chamber in
applications where the actuator is located in an aggressive
corrosive atmosphere. As an option the Pneumatic Module can
be equipped with a speed control.
Dual Stroke Limit Stops
FieldQ actuators are factory set on a rotational travel
of 90°±0.5°. Two limit stops are available as standard to
adjust either the open and/or closed position. With the dual
stroke limit stops, a wide variety of valve applications,
like metal seated or high performance valves, can be
adjusted accurately to their specific requirements.
Intelligent Position Tracking Device
IPT
technology™ allows the integration of controls and feedback
in a single product - providing continuous position
tracking, with contactless position sensing and feedback. A
separate switch box, found on other actuators, has been
replaced by an integrated sensor on the pinion. This
continuously monitors movement and communicates feedback to
the Control Module and back to the control room, as
required.
Pinion
Precision-machined
anti-blow-out pinion is made of high duty aluminum alloy and
hard anodized for optimum performance and durability. Three
part pinion design is balanced, reducing pressure forces on
the pinion thrust, radial bearings and the O-ring seals.
This ensures low maintenance requirements in high cycle
applications. Seals are designed to minimize crevices,
providing maximum protection against corrosion. The Delrin
radial bearing on the pinion bottom is made as wide as
possible to minimize friction and ensure a durable and
smooth operation.
Limit Stop Cam
The large diameter,
high tensile steel, limit stop cam ensures accurate and
lasting stroke adjustment.
Body
Superior materials
and coatings provide optimum strength and corrosion
resistance, ensuring long service life and minimal
maintenance through corrosion issues.
Piston
The large piston rack is precision-machined and
chromatized for optimum performance and lasting durability.
Nitrile rubber O-ring seals and the 3 point guiding system
ensure a durable, air tight and smooth operation.
Spring Package
Single acting actuators up to size Q350 have spring
packages for safe and easy disassembly, requiring only
standard Allen keys.
End Cap
End caps on double acting versions Housing Guide Band
are flat, reducing overall length.
End Cap Screws
Valve Flange All external fasteners are stainless
Housing Guide Band
Wide Nylatron® guide band provides wear protection
between housing and piston, extending actuator life in the
most severe and demanding conditions.
Valve Flange
FieldQ actuators are all provided with valve flanges
according to ISO 5211. Most sizes have two drilling patterns
and together with the insert provide a low cost and
versatile direct valve mounting. For mounting according to
DIN3337 the glass filled nylon centre plate is added to the
actuators flange, providing additional location of the
actuator to the mounting bracket. |
