NEW PRODUCTS TO POWER YOUR BUSINESS
High-Capacity Safety Valve
Pentair Valves & Controls' newly introduced
Crosby HCI ISOFLEX is a high-capacity safety
valve to help power plant operators reduce
lifecycle costs and minimize shutdown
periods. The valve ensures cost-effective
power plant operation with a unique fullnozzle,
flanged design and adjustable lift
option that reduces maintenance costs while
maximizing plant efficiency. Specifically
designed for 300 to 3,000 psig steam
generators, the HCI ISOFLEX can withstand temperatures up to
1,100F/593C and is available in various inlet sizes, ranging from
1½ inch (38.1 mm) to 6 inches (15.24 cm). An extensive range
of interchangeable spare parts enables operators to repair or
exchange components individually, avoiding costly replacements and
minimizing shutdown time.
The valve is also available with an optional restricted lift feature
to eliminate overcapacity and ensure a more economic distribution
of relieving capacity between the drum and superheater safety
valves. This design not only reduces reaction forces for a greater
lifespan but also allows for the use of smaller superheater safety
valves in some operations, reducing overall installation costs.
Additional benefits include precise blowdown control due to a tworing
design and exceptional seat tightness up to 95% of valve set
pressure. (valves.pentair.com/valves)
Shaft Alignment
Phone/Tablet App
LUDECA released a new version
of its " Laser Align " mobile
application. The application
provides a free reference tool
for shaft alignment of rotating
equipment. It allows users to
access important reference
material and learn about key
laser shaft alignment concepts,
and it now has an interactive
" Tolerance Table. " When users
input their machine's revolution
per minute measure using this
feature, the app will kick back the
respective alignment tolerances
for both short-flex and spacetype
couplings. It also includes
a thermal growth calculator and
now has a " soft foot assistant "
to help the user interpret soft
foot values. The app is available
for free in the iTunes Store for
both iPhone and iPad, as well as
in Google Play for the Android
market. (www.ludeca.com/res_

New Abrupt Arched Expansion Joint
The new Garlock 204 EPS (extreme pressure service) abrupt arched
expansion joint is now available for applications where necessary
rated pressures exceed those of the Garlock Style 204 and 204
HP designs. Fully customizable and available in concentric or
eccentric designs, the expansion joint features a seamless tube
to ensure a reliable seal from flange to flange. High pressure and
vacuum resistance increase safety and ensure the joint's suitability
for a range of applications. The tube can be manufactured in a
wide selection of elastomers that are resistant to temperatures,
weathering, oxidation, and chemicals, and the abrupt arch
configuration provides
maximum movement,
and pressure and vacuum
resistance. The joint's body
is made of a composite fabric
construction with welded,
treated metal body rings for
dimensional stability. (www.
