Smart actuator optimizes control valve performance
The new Smart Electric Valve Actuator (SEVA) from Badger Meter stands up to extreme
conditions while providing exceptional position accuracy
ince 1905, Badger Meter has been recognized as a leader
in the development and manufacture of flow management
solutions. The company has introduced the latest
generation of its Smart Electric Valve Actuator (SEVA) solution,
which now offers Modbus RTU, Modbus TCP/IP and
SoloCUE® connectivity.
SoloCUE connectivity
SoloCUE is a software solution that provides easy
access to the setup of both the feature-rich SEVA and
its protocols. This custom-built, bulletproof platform allows
end-users to visualize SEVA's performance and setup
characteristics.
Product design
SEVA employs cutting-edge technology and delivers exceptional
accuracy and repeatability. Designed for extreme conditions,
the actuator has military-grade components.
SEVA has 100-lb. and 200-lb. thrust models. There are sevS
eral
options available for communication protocols, including
Modbus RTU, Modbus TCP/IP and the Industrial Ethernet Protocol
(EtherNet/IP). It is is certified by FM, EX, CSA and CE. The actuator
allows for both linear and Device Level Ring (DLR) ring network
topologies.
Position accuracy
SEVA provides an exceptional level of position accuracy (±1%
of full scale) with five available positions when there is a loss of
power. The device also features four positions when
there is a loss of signal. Both the full closed and full
open positions are defined during setup.
In addition, SEVA has an internally powered (active)
feedback signal, which actively communicates
stroke position to the control system. Its feedback
sensors are crucial in more precise applications.
SEVA even provides a manual override capability to
help the operator in loss-of-power situations.
Other features
The SEVA assembly has the option to include two
user-adjustable limit switch outputs. An external signal is
provided once the set points of the limit switches are met.
Furthermore, the electric actuator can split the incoming
4-20 mA signal and use either the lower or higher range
of the signal for full stroke operation. A hyper terminal
server makes it possible to change the type of split range.
SEVA was specifically designed to minimize the number
of models needed to work with different electrical
demands. Its Universal AC Input with voltage protection will work
with 115 V AC, 230 V AC and 24 V DC power supplies. This feature
ensures confidence that the actuator will provide a single source for
different process needs. SEVA can receive analog input signals from
4-20 mA, 0-5 V DC or 0-10 V DC.

Partners in a Sustainable Plastic Revolution
How Loop's disruptive depolymerization technology is changing the plastic world
ost plastic and fiber production today is a classic example of
wasteful linear economy. But in 2014, a small innovative company
set out to disrupt traditional plastic and fiber manufacturing
by up-cycling with waste. Starting in an improvised lab located in
a garage, Loop Industries created a revolutionary low-energy depolymerization
technology that transforms low value and no value
waste plastic into high-value chemicals used to produce virgin-quality
PET plastic for use in food-grade packaging, like the kind used to
make water bottles. In addition to reducing greenhouse gas emissions
and dependence on fossil fuels, Loop's technology also dramatically
reduces environmental impact by diverting PET plastic and
polyester fibers from oceans and landfills.
Putting the Revolution In Operation
Through its vision, Loop Industries had set in motion a sustainable
plastics revolution.
But as a start-up company,
to ensure business success
they needed to partner with
a process simulation software
provider that could accommodate
their budget,
provide expert technical
support, and have the ability
to scale to meet Loop's
needs as it grew. After evaluating
several different proM
cess
simulation software companies, Loop chose Chemstations due
to its modular customization, easy integration, flexible licensing,
expert technical support and affordability.
Proving Chemistry Viability
By selecting CHEMCAD from Chemstations, Loop Industries benefitted
from a suite of six modules that could be purchased individually
or bundled as needed to accommodate Loop's budget and
processes. Loop also received personalized guidance from multilingual
support staff and high-level engineers from Chemstations
who worked to ensure simulations went smoothly and that the
chemistry was viable. In addition, Loop had 24/7 access to a library
of training videos on the CHEMCAD customer portal. During the
simulation process, Loop used the operating settings based on the
CHEMCAD CC-BATCH module simulation results to run the three different
distillation stages of Methanol Recovery, Water Removal, and
MEG Purification. Based on the successful pilot results, Loop created
initial documentation around its technology that confirmed its
viability to the market.
Driving Productivity and Growth
With the software simulation and proactive technical support
provided by Chemstations, Loop has created a truly circular supply
chain for one of the world's most widely used plastics. Throughout
its growth, Loop's relationship with Chemstations has also grown.
Today, Loop relies on the full CHEMCAD-SUITE of products to tackle
their toughest process models. For more information, visit
