TVS 4000 Trap Valve Station
Armstrong Packaged Piping Solutions Simplify Your Steam Tracing Line Systems
Designed to simplify and supply all the components (steam
traps, manifolds, valves, etc.) necessary for your drip and
tracer line applications, Armstrong’s Steam Distribution,
Condensate Collection Manifolds, and Trap Valve Stations
bring all components together to reduce installation costs
and provide a compact, easily accessible, centrally located
assembly.
many great benefits—cost savings in installation, design
flexibility, reduced purchasing time, and provides personnel
safety. The model CCAF also includes syphon tube freeze
protection.
Steam Distribution Manifolds
The TVS 4000 is a connector that packages two piston-style
isolation valves, test valve and stainless steel strainer with
blowdown valve into one connector. This connector can
accommodate a choice of inverted bucket, disc, thermostatic
wafer, thermostatic, bimetallic or float and thermostatic style
Armstrong steam traps. Any other manufacturer’s 2-bolt
steam trap can also be applied to the Armstrong TVS 4000
Trap Valve Station.
TVS 4000 Trap Valve Station With Integrated
Valves Reduces Piping Costs and Saves Space
As a Steam Distribution Assembly (MSD/SMSD), the manifold
places all steam supply valves in one location. Standardizing
components and centralizing their location simplifies installation,
cutting costs from the beginning and increasing safety. You
also save because routine maintenance is faster.
Condensate Collection Manifolds
To make industry’s trapping and valving more efficient,
Armstrong combines its TVS 4000 stainless steel trap valve
stations with manifolds into a package called the Condensate
Collection Assembly (CCA). This prepackaged assembly offers
Steam Distribution and Collection
Whatever your condensate collection or steam distribution
needs, Armstrong has the packaged solution for savings
over the long term.

Pre-Assembled… Condensate Collection Assembly (CCA)
Design Flexibility
Armstrong combines its Trap Valve Stations (TVS) with
manifolds into a package called the Condensate Collection
Assembly (CCA). This prepackaged assembly offers many
great benefits—cost savings in assembly, design flexibility
and reduced purchasing and design time. The CCA with
TVS 4000 trap valve station and 2000 Series Inverted
Bucket Traps is guaranteed for 3 years.
Armstrong can meet virtually any design parameter,
including dimensional consistency, with your choice of
socketweld or threaded connections. Armstrong inverted
bucket, thermostatic, thermostatic wafer, bimetallic or disc
steam traps can be provided or any other manufacturer’s
two-bolt steam trap can be used. If you require a specific
piping arrangement, Armstrong can offer the flexibility to meet
your specifications.
Cost Savings
This preassembled concept offers tremendous savings by
reducing multiple component purchases that cause additional
purchase order monitoring and shipping costs. Other savings
include far less labor time required for field assembly.

Bucket all stainless steel steam traps with optional removable
insulation package including nipples, drain valve and stand.)
A manifold assembly for more efficient condensate return
has another benefit—freeze protection. Armstrong’s
innovative manifold design actually serves as a heat station,
heating one or more traps if the steam supply is interrupted
or shut off to the traps. The protection is accomplished as
long as one trap continues to discharge into the manifold.
The manifold’s internal syphon tube creates a water seal,
which contains the flash steam from the discharge of the live
trap. This allows radiant heat to protect shut-off traps from
freezing.
An optional freeze protection valve package senses
condensate temperature. When this device opens, it drains
condensate from the manifold assembly, thus providing
further freeze protection.

• Dual sealing action. The piston valve is a seatless valve
that includes two graphite and stainless steel valve sealing
rings that seal the stem and function as a seat. This
combination provides long-term protection against leaks to
the atmosphere and downstream piping.
combination of disc springs and dual valve seal rings
protects against expansion and contraction due to heating
and cooling. This ensures dependable operation, even after
years of service.
• Protected valve stem. The valve stem and sealing surfaces
are completely protected from dirt and corrosion by the stem
cap, whether in an open or closed position.
• Self-cleaning action. Stainless steel piston slides without
rotating between the two valve sealing rings, preventing dirt
from damaging the surfaces.
• In-line repairability. All sealing valve components may be
easily replaced in-line.
• Sealing integrity. Flexible disc springs automatically
provide leak tightness by exerting pressure, which keeps the
upper and lower valve sealing rings compressed at all
times. Sealing tightness is ensured by the compression
of the sealing rings against the piston and valve body. This
• Long-term operation. Piston valve design ensures actuation
even after many years without operation.

For Pressures to 400 psig (28 bar)...Cold Water Start-Up Capacities to 1,300 lb/hr (590 kg/hr)
Description
The WT-2000 thermostatic wafer steam trap is adaptable to a 360°
connector to expand piping options and simplify installation.
NOTE: Since the normal operation of all suppressed temperaturedischarge (subcooling) steam traps is to back up condensate, they
should not be used on drip legs for saturated steam service,
heating or process equipment. Exercise care in the maintenance of
any thermostatic wafer trap with a small discharge area susceptible
to clogging.

How to Order WT Series Thermostatic Wafer Steam Trap
Specify:
• Model number
*Capacities based on differential pressure with no back pressure.
**Capacities will vary with the degree of subcooling. When greater capacities are
required, the trap will automatically adjust to the load, up to the maximum (cold water)
capacity shown, by increasing the amount of subcooling.

Wafer Steam Trap
AB-2000 Bimetallic Steam Trap
All Stainless Steel
For pressures to 320 psig (22 bar)… capacities to 4,630 lbs/hr (2,100 kg/hr)
Description
Armstrong’s AB-2000 Bimetallic Steam Trap operates by the effect
that rising temperature has on bimetallic elements. It adjusts itself
to changing conditions, as the increasing pressure on the valve is
compensated by the curving of the bimetallic elements caused by
the increasing temperature. The valve of the AB-2000 is specially
treated (boronization) in order to be more resistant to wiredrawing
due to erosive condensate flashing.
Armstrong’s AB-2000 has a sealed, stainless steel body that is
lightweight, compact and highly resistant to corrosion. It is
adaptable to a Armstrong 360° Universal Connector or a Trap Valve
Station (TVS). This makes it easy to install and replace, as the trap
can be removed while the connector remains in-line. The result is
savings in labor cost and increased flexibility, as other trap types
(Inverted Bucket, Thermostatic, Thermostatic Wafer, Disc and Float
and Thermostatic) can be installed on the same connector.
Specification
See Page 40.
Valve Boronized
How to Order
The problem of wiredrawing the valve and seat materials is well
known to users of steam traps and other types of valves.
Wiredrawing is a particular problem with valves and seats in
bimetallic traps, which rely on bimetallic elements to operate.
Specify:
• Model number
To solve the problem of wiredrawing, a new thermochemical surface
treatment has been developed. The basic valve material is
machinable hardened chrome steel. Atoms of highly resistant
material are thermochemically diffused into the valve, giving a layer
of protection and a hardness of 1700 HV to the basic material.
Because of this new thermochemical treatment, the surface of the
valve is highly resistant to the erosive action of flashing condensate.
The failure rate of Armstrong bimetallic traps due to wearing out of
valve and seat material is greatly reduced.

SH Series Superheat Traps
Bimetallic Steam Traps for Superheat Conditions
For pressure to 1,500 psig (104 bar)… cold water capacities to 6,500 lb/hr (2,950 kg/hr)
Description
Armstrong’s SH Series Bimetallic Steam Traps for superheat or low
load conditions are the ideal traps for applications where other trap
styles are not suitable for long life.
The Armstrong SH series bimetallic traps also have the ability to
handle the large start-up loads associated with superheat
applications. The unique bimetallic element allows for shut-off before
superheat reaches the trap thus preventing steam loss. The SH
900/1500 series utilizes titanium valves and seats to ensure
extremely long service life in the harsh environment of superheated
steam systems.

Pump Trap System Applications
Flare Header Drain
This pump trap system design allows for continuous drainage of
hydrocarbon condensation that could result in a liquid slug being sent
from low points in the header to the flare. This slug condition can cause
water hammer, and potentially extinguish the flare. This system allows
customers to run feed lines to an existing flare system even though it
may have low points due to elevation changes. Utilization of this pump
trap system can eliminate the need for a new flare, or minimize
required piping to tie in to an existing system. The liquid drainer
installed downstream of the pump prevents hydrocarbon gas flow into
the liquid reclamation piping. A process upset could cause an increase
in flare header pressure, and create a positive differential. Since the
liquid drainer is designed to maintain a liquid seal, it will not discharge
process gas, only liquid. A ready source of inert gas, such as nitrogen
must be used as the pump trap's motive. As numerous potential gases
could be introduced into this system, verification of the lightest specific
gravity fluid must be confirmed.
Hydrocarbon Knock-Out Drum / Separator
Numerous processes in the HPI/CPI industry require liquid
removal from a process gas before the next stage of the
process can be undertaken. This pump trap application allows
for a more cost-effective alternative to explosion proof motors
and pumps in a separation area. Typical applications require a
small pump to handle very light loads. Verification of the
specific gravity of the liquid produced by the separation
process is critical. A ready source of inert gas, such as
nitrogen, must be used as the pump trap's motive fluid.
Process Exchanger with 100% Turndown Capability
This pump trap system application allows customers to maintain a
totally dry heat exchanger, regardless of the condensate rate that is
being produced, or the efficiency of the tube bundle. Variable pressure
and condensate rates are common as production demands fluctuate.
The elimination of tube bundle corrosion and potential tube failure,
causing a production interruption, are the primary benefits of this pump
trap system design. Reboilers with excessive surface area commonly
run in vacuum due to lower process flow rates produced, and process
outlet temperatures required. The pumping trap ensures removal of the
condensate against backpressure, which is almost always caused by
condensate return lines being overhead. This allows the exchanger to
run at it's lowest required pressure, which minimizes energy
consumption due to the latent heat content of the lower pressure
steam. As the heat exchanger becomes fouled due to coking or the
adhesion of burnt product to the tube wall, it becomes less efficient.
This mandates the increase of higher temperature / steam pressure
from the control valve to accommodate the lack of btu transfer. This
scenario typically exceeds the backpressure, creating the need for the
downstream trap to stop the flow of steam until condensed. Variable
condensate rates and fouled surface areas are "real world" problems
that create the opportunity to design a condensate system that
performs flawlessly, regardless of the conditions.

Pump Trap System Applications
Vacuum Reboiler / Heat Exchanger
Construction Comparison
When draining vacuum systems, Net Positive
Suction Head [NPSH] is critical for the proper
operation of a typical electric condensate pump.
The use of pumping traps can minimize the skirt
height required for the reboilers or exchangers,
which will save thousands of dollars in construction
costs. This savings alone can justify the use of this
pump trap system. A typical system designed for
full vacuum would require a 40 ft. elevation to drain
to a conventional condensate pot with level control.
This could be reduced to as low as 4 ft depending
on the flow rate and head required for the pumping
trap system.
Flash Tanks
As numerous plants utilize a cascading steam system to optimize
steam usage, pumping traps offer many advantages for receiving
condensate. If electric pumps are used, the height of the flash tank
must accommodate NPSH requirements. The typical temperature of
medium to low pressure condensate drained from these tanks is also a
major concern for cavitation in most electric pumps. The ability of the
pump trap to pump condensate at its highest possible temperature,
with the flash tank at minimal height, is a great benefit to the user.
Steam Turbine Drainage
Almost every Refinery and Chemical plant utilizes steam turbines.
The vacuum side of the turbine's outlet directly equates to its
efficiency. The higher the vacuum, the more efficient it is. Draining
the condensate from turbines is critical, as a typical turbine rebuild is
very costly. Specially designed pumping trap systems offer more
longevity and dependability than conventional steam eductor methods.
Eliminating steam consumption of the eductors alone can justify the
installation of pumping trap systems.

NOTES: Published capacities are based on the use of external check valves supplied by Armstrong. Fill head measured from drain point to top of pump cap. Although motive pressures
are shown at high pressure differentials (difference between motive inlet pressure and total lift or back pressure), it is preferable to use a motive pressure
of 10 - 15 psig (0.65 - 1 bar) above discharge (outlet) pressure. This ensures longevity of stainless steel check valves and reduces both venting time and temperature differential
(on steam).

NOTES: Published capacities are based on the use of external check valves supplied by Armstrong. Fill head measured from drain point to top of pump cap. Although motive
pressures are shown at high pressure differentials (difference between motive inlet pressure and total lift or back pressure), it is preferable to use a motive pressure of
10 - 15 psig (0.65 - 1 bar) above discharge (outlet) pressure. This ensures longevity of stainless steel check valves and reduces both venting time and temperature differential (on
steam). *Consult factory.

PT-516 High Capacity Pump Trap
Effective recovery and return of hot condensate are essential
to overall plant efficiency while conserving energy. Large amounts
of condensate provide the best opportunities to save energy.
The Armstrong PT-516 high capacity pump trap is the low
maintenance, non-electric solution to moving large amounts
of condensate and other liquids from low points, low pressures
or vacuum spaces to an area of higher elevation or pressure.
Condensate can be returned at temperatures well above the
210°F (99°C) limit of conventional electric pumps without the
headaches of leaking seals or cavitation.
Features
the pump trap
• No leaking seals/packings, impeller wear, electrical or motor
problems—Reduces maintenance and downtime
• Single trade installation or repair reduces installation
and maintenance costs
• Direct spring/float actuated mechanism — (No maintenance
intensive diaphragm operated valve mechanism)
• Compression spring design—Reduces downtime, ensures
performance and reliability
• Rugged stainless steel internals—Durable and corrosion
resistant for enhanced service life
• Safety—Pump can be placed in flooded pits without fear
of electrocution or circuit breaker defaults
• Explosion proof—Standard unit intrinsically safe without
additional cost

Reduce implementation conflicts. Data from
3rd party software or Microsoft Excel can be
import to the SteamStar™ platform. This feature
makes SteamStar™ a non-binding platform
designed for easy company wide usage.
• Eliminate costs associated with software
licensing agreements. Licensing agreements
can cost ten’s of thousands of dollars for initial
software purchase. For the software to facilitate
multiple user, additional capital outlay is
required. The web-based platform of
SteamStar™ eliminates licensing fees and
dramatically reduces the required investment. A
one month return on investment!
• Improve Steam System Efficiency. Steam
system efficiency can be directly linked to how
well the system is managed. SteamStar™

goals are measured, monitored, and managed
on a consistent basis. SteamStar™ is the web
based tool that will bring data together by site,
by region and by company to help achieve best
practice energy management goals.
• Save valuable time. Typically steam trap data is
presented from multiple sites in different
software formats and with different qualifying
terminology. These variables make managing
steam system information difficult and time
consuming. SteamStar™ offers a platform for
company wide steam data to be viewed and
analyzed without wasted time.
• Improve company wide communication. Users
at the plant level can perform evaluations to
determine root causes of steam system issues.

SteamStar™ web-based platform will…….
Evaluate Steam System Data
Detailed analysis of all site surveys can be evaluated
using the many standard reports available on
SteamStar™. The executive summary highlights total
site energy losses and current steam trap failures.
This report is critical in establishing a base line for
future achievement of company energy goals. Other
standard reports are:
• Steam and Monetary Loss
• Defective Trap Report
• Manufacturer Summary
• Trap Evaluation by Application
Steam management not only helps to mitigate steam
losses but it also facilitates educated decisions about
the type of technology used. All of the standard
reporting capabilities of SteamStar™ provide a site
with actionable data in a user friendly format.
Work Order Report
The work order report is a premium report that was
designed for optimum facility payback on labor and
material while keeping energy losses to a minimum.
This report is available at the site or unit level and will
create a work order for steam trap repairs based on
payback. A facility with dedicated, trained personnel
for steam trap maintenance is very rare. Quick
determination of areas losing the most money is
invaluable when trying to allocate labor for various
important facility activities.
Work Order Report
Benchmark
A premium report that establishes a comparison to
sister sites and industry peer best practices. The user
has a choice of which sites to benchmark and which
factors to compare. Steam losses and monetary losses
can be compared by site, by type of application, by
type of trap, and more. This report will offer
management a wide analysis of which sites are
working to reduce steam losses and which lag behind.
It will also highlight any areas of concern in terms of
high steam trap failure rate compared to total
monetary losses. This report is a valuable tool for
facility mangers and global energy managers alike.
Trend
The premium trend analysis report will assist a
manager with the comparison of multiple years of data.
The data available for comparison is steam loss,
monetary loss, fuel consumed, and emissions created.
Like the other premium reports, the trend analysis
report can be compared by site and or region. This
report will emphasize sites or units that are actively
pursuing company best practice goals for steam
system management. It will also track emissions; CO2,
SOx, NOx, and highlight the progress made toward
steam system efficiency and dollars saved.
Emission Report
The premium emission report is valuable for its ability
to focus on the quantifiable emissions of CO2, SOx,
and NOx in one summarized view. Steam system
efficiency is not only viewed as important in terms of
energy losses but also in terms of environmental
impact. The emission report is especially beneficial to
users who are penalized by world governments for
high emission factors.
