ENERTECH, a business
unit of Curtiss Wright
Flow Control Company,
has developed an extend-
ed mission model to sup-
port nuclear plant cool
down during station black
conditions. Conventional
electrohydraulic, gas
spring actuators are lim-
ited to one direction—fail
safe positioning of isola-
tion valves. Enertech’s
advanced technology permits bi-directional, mid-position
cycling of throttling valves and dampers from stored ener-
gy for a 72-hour period or longer without dependency on
off-site power, emergency diesel generator power or air
supply. The space required to facilitate the stored energy
module is a fraction of that required by traditional air sup-
ply tanks and control panels used in early generation
nuclear plants.
ITT ENGINEERED VALVES introduces
the Fabri-Valve 33 PTA push-through
slurry valve, specifically designed to
withstand harsh slurry applications in
the mining industry. It incorporates proprietary sleeve technology and a wide
body design, which increases the valve’s
life span in slurry applications.
The product has elastomeric seats
that have been engineered to provide the
highest degree of abrasion resistance and
chemicals compatibility. The valve seats
form a pressure boundary, allowing the
gate and actuation to be maintained
while under pressure, ultimately reducing
downtime.
METSO offers a new valve
design derived from their traditional V-port segment valve
series. The two-way-tight, single-seat design is suitable for
numerous applications and is
available for R-series valves.
The optional two-way-tight
feature covers size ranges
from DN25 up to DN700 ( 1”
up to 28”) in all available
pressure classes.
The V-port segment valve series is designed to improve
process performance and reduce variability in control
applications. However, there are a lot of applications
where two-way-tight, on-off type performance is required.
The customer benefit of the new valve design is that it
offers the possibility of combining control and on/off performance in a single valve assembly.
MUELLER CO., a
wholly owned sub-
sidiary of Mueller
Water Products, Inc.,
has expanded its prod-
uct line with the addi-
tion of the Hydro-
Guard brand of
automated flushing
systems. The system
uses modern technologies, including SCADA compatibility,
to monitor water quality in distribution piping and auto-
matically initiate flushing as necessary to maintain disin-
fectant residuals as required by the U.S. Environmental
Protection Agency. This system conserves water, reduces
chlorine consumption and improves customer satisfaction
by avoiding taste and odor, while requiring virtually no
supervision by utility personnel. On average, one Hydro-
Guard Automatic Flushing System can save as much as
180,000 gallons of water annually compared to traditional
hydrant flushing methods.
ASCO NUMATICS
has introduced the
8361 Series of stainless-steel pilot valves.
The series’ unique
design eliminates the
dormancy or sticking
problems that can
occur in control valves
installed in the pneumatic logic panels that
control monitoring
safety systems in offshore oil and gas production facilities. In addition, the
valve line was launched with online tools that permit rapid
product configuration and ordering.
The 8361 Series (¼-inch NPT, 3-way, 316L stainless
steel) valves are offered in manually operated, air-piloted
and solenoid-piloted versions. They can be configured as
breathing and non-breathing. The non-breathing version
isolates internal components from the atmosphere and is
