Turbine Bypass-Bypass
Valves-Angle-
Flow Up, TBX
 |
TBX Series valves reduce
both steam pressure and
temperature to enable
daily cycling of a power
plant. In addition, they
protect reheater tubes,
condenser, and piping
against excessive
pressure, temperature,
and enthalpy excursions
during steam turbine
trips.

Turbine Bypass-
Valves-Globe-
Hybrid Globe & Cooler
 |
Combined pressure and
temperature control for
low pressure
applications. Multiple
globe designs available
coupled with integrated
cooler section to match
service requirements in
an in-line orientation.

Turbine Bypass-
Spargers
 |
Design TBX sparger is a
back pressure device
that is an integral part
of a well designed
turbine bypass system
when discharging to
either water cooled or
air cooled condensers.
The design is critically
important to minimize
system noise and
optimize turbine
efficiency.

Other Engineered
Valves-
Polymer Flow Control
 |
The HVP design
incorporates a
continuous flow path for
viscous polymer fluids
at sustained high
temperatures to prevent
freezing and product
degradation.

Desuperheaters/Attemporators-
Interstage Attemporators
 |
Design DMA/AF HTC is
used in cycling service
common to superheater
interstage attemporators
and severe service
applications that have a
significant difference
in steam and water
temperature and are
subject to high
vibration.

Desuperheaters/Attemporators-
Multi Nozzle/High
Capacity Steam Cooler
 |
Design TBS-T steam
coolers have multi
nozzles producing fine
spray for rapid
vaporization. The steam
cooler section can
accommodate a silencer,
which decreases steam
pressure energy in a
controlled velocity
expansion.

Desuperheaters/Attemporators-
Mechanically Atomized
 |
Design DMA is a simple
mechanically atomized
desuperheater with
single or multiple,
fixed-geometry spray
nozzles intended for a
steam conditioning
applications with nearly
constant load.

Desuperheaters/Attemporators-
Spring Loaded, Variable
Geometry
|
Design DMA/AF is a
variable-geometry,
mechanically atomized,
back-pressure-activated
superheater interstage
attemporator, designed
for applications
requiring control over
moderate load
fluctuations and high
thermal cycling.

Desuperheaters/Attemporators-
Self Contained, Variable
Geometry
 |
Design DVG/AF is a
variable-geometry
mechanically atomized,
self-contained steam
conditioning
desuperheater for
moderate to high flow
variation.

Desuperheaters/Attemporators-
Steam Assisted
 |
Steam conditioning
Design DSA desuperheater
uses high-pressure steam
for rapid and complete
atomization of
spraywater in
low-velocity steam
lines.

Desuperheaters/Attemporators-
Venturi
 |
Steam conditioning
Design DVI desuperheater
injects spraywater in
the outlet of the
venturi section,
assuring excellent
mixing and rapid
atomization.
