10 | Nonstop High-Cycle Applications
Improve Uptime with Sliding-Stem Control Valve Assemblies
On-Line, In-Service Diagnostics
When coupled with ValveLink software,
FIELDVUE digital valve controllers give advanced
notice of performance issues and provide
recommended actions.
•
Reliable Actuator Performance - Special GX actuator diaphragm
material helps reduce common problems such as air oxidation,
thermal aging, low temperature embrittlement, and loss of
retention. Unlike a piston actuator, the GX spring-and-diaphragm
actuator does not have a large diameter sliding seal that is subject
to wear. The double-sided diaphragm within the actuator helps
eliminate mechancial wear-induced failure.
•
Fast Stroking Speed - When your high-cycle applications require
adjustable cycle times, Fisher control valve assemblies deliver with
fast actuator stroking speeds and tight process control.
•
Precise Valve Positioning - Linkage-less, non-contact FIELDVUE
digital valve controllers are paired with Fisher control valves to
achieve precise positioning accuracy and fast response to process
changes. FIELDVUE digital valve controllers offer integral 4-20 mA
position feedback for explosion-proof or non-explosion-proof
applications.
Enhanced Stem Alignment
The stem connector eliminates axial load on
the packing system, improves the stem seal,
and increases packing life.
Zero Lost Motion
With no linkage to wear,
loosen, corrode, or vibrate,
FIELDVUE digital valve
controllers can handle harsh
environments and nonstop
cycling. A magnet array and
Hall Effect sensor are used to
detect valve position.
Pushbutton Calibration and Versatility
Configure, calibrate, and tune the FIELDVUE DVC2000
digital valve controller using its local user interface
with four pushbuttons. Users can select their language
of choice, which allows for global standardization.
