Badger Meter
tom-built, bulletproof platform allows
end-users to visualize SEVA's performance
and setup characteristics.
SEVA is designed for extreme conditions,
and the actuator has militarygrade
components. SEVA has 100and
200-lb thrust models. There are
several options available for communication
protocols, including Modbus
RTU, Modbus TCP/IP and the
Industrial Ethernet Protocol (EtherNet/IP).
It is certified by FM, EX, CSA
and CE. The actuator allows for both
linear and Device Level Ring (DLR)
ring network topologies. - Badger

All-in-one pump protection
automatic recirculation valves
The new, self-modulating TDL Automatic
Recirculation Valves (photo)
in 10 and 12 NPS are now available
with high bypass flow, offering
maximum flexibility in bypass trim
sizes for pumping systems. These
reliable all-in-one pump-protection
valves are designed to keep pumping
systems modulating and running
smoothly, without cavitation, vibration
or overheating. Without minimum
flow, a pump can quickly suffer
grave damage, causing downtime
and costly
repairs - but control
Emerson
valves for recirculation require continuous
control of complex equipment,
a flow measurement device,
control unit and energy supply. Unlike
control valve packages, these
self-operated flow-sensitive valves
operate without a separate power
supply or any control system, and
begin protection immediately once
installed. - Schroedahl GmbH, a

New virtual valve-repair service
offers immediate support
The new Remote Assistance service
capability (photo) was launched in
April to help plant operators immediately
respond to industrial valve issues
by using augmented reality (AR)
technology. The AR technology uses
a robust, secure channel certified as
ISO 27001-compliant. Valve repairs
are advised and guided by this company's
experts as part of its expanding
Connected Services portfolio in its
Plantweb digital ecosystem. Using a
mobile device, plant personnel can seA
host of check valves for
trouble-free performance
This company's Surgebuster, Dual
Disc, Silent Check and Sure Seal
Foot Valve check valves are highly
engineered to provide long life and
trouble-free performance. Engineers
weigh the importance of slamming
characteristics as one of the factors
when selecting a check valve. All
check valves are designed with nonslam
characteristics, such as the
seat angle of the Surgebuster. The
Surgebuster also uses the addition
of the Disc Accelerator to prevent
slamming in the most severe applications.
The compact wafer design has
made the Dual Disc a popular choice
when space is a concern. The short
linear stroke and spring-return action
of the Silent Check Valve combine
to effectively eliminate surges and
water hammer that can be associated
with the sudden stoppage of a
reverse flow. The versatile Foot Valve
can provide positive seating action at
both low and high pressure without
slamming. - Val-Matic Valve & Manufacturing

A new, enhanced
digital smart positioner
The new enhanced YT-3700 and
YT-3750 digital
smart
curely share their field of view through
the AR software as valve experts help
troubleshoot and solve valve problems.
Step-by-step instructions are
overlaid in the field-user's application
to support installation, calibration or
repair actions. The Remote Assistance
service is available for this company's
valve, actuator and regulator product
portfolios, and in some instances, can
cover other companies' products. -

positioners
(photo) can be used for both control
and on/off valve applications where
diagnostics are required. The YT3700
and YT-3750 pneumatic smart
positioners employ continuous monitoring
and graphic display of valve
position, setpoint target over time
and internal circuit board temperature
over time. Valve diagnostic information
to NE107 standard is provided,
with HART 7 communication
protocol included as standard and a
display for all settings and local device
interaction. Commissioning can
