Introduction
Thank you for purchasing the TLV PowerDyne thermodynamic steam trap.
This product has been thoroughly inspected before being shipped from the factory.
When the product is delivered, before doing anything else, check the specifications and
external appearance to make sure nothing is out of the ordinary. Also be sure to read
this manual carefully before use and follow the instructions to be sure of using the
product properly.
This trap unit is of a revolutionary design that uses a high-performance universal flange
and features a built-in automatic blow-off function and will function as a trap when
installed onto a two bolt connector in the existing pipeline. As it includes a built-in
screen with a large surface area this trap unit is intended for use with connector units
that do not have a built-in screen (Spirax Sarco: PC10, Armstrong: Standard
Connector). The universal flange allows the trap to be installed in either horizontal or
vertical piping. This flexibility greatly reduces the time required for installation and
removal, as compared to conventional steam traps, and also facilitates repair and
maintenance operations. This PowerDyne thermodynamic steam trap features a
bimetal ring for thermostatic air venting, which allows the quick, automatic discharge of
large quantities of initial air and cold condensate immediately after operation start-up,
thereby greatly reducing start-up time. This PowerDyne thermodynamic steam trap,
with its superior features listed above, in combination with the proven performance
record of the bimetal thermostatic air vent, increases heating efficiency and reduces
manpower requirements for maintenance and bypass blowdown.
If detailed instructions for special order specifications or options not contained in this
manual are required, please contact TLV for full details.
This instruction manual is intended for use with the model(s) listed on the front cover. It
is necessary not only for installation, but for subsequent maintenance, disassembly/
reassembly and troubleshooting. Please keep it in a safe place for future reference.

Checking the Piping
Use only under conditions in which no water hammer will occur. The
impact of water hammer may damage the product, leading to fluid
discharge, which may cause burns or other injury.
CAUTION
Check to make sure that the pipes to be connected to the trap have been installed
properly.
1. Is the pipe diameter suitable?
2. Has sufficient space been secured for maintenance?
3. Have isolation valves been installed at the inlet and outlet? If the outlet is subject to
back pressure, has a check valve (TLV-CK) been installed?
4. Is the inlet pipe as short as possible, with as few bends as possible, and installed
so the liquid will flow naturally down into the trap?
5. Has the piping work been done correctly, as shown in the figures below?
Requirement
Correct
Incorrect
Install catchpot with the
proper diameter.
Diameter is too small.
Make sure the flow of
condensate is not
obstructed.
Diameter is too small and inlet
protrudes into pipe interior.
To prevent rust and scale
from flowing into the trap,
the inlet pipe should be
connected 25 –50 mm (1
–2 in) above the base of
the T-pipe.
Rust and scale flow into the
trap with the condensate.
When installing on the
blind end, make sure the
flow of condensate is not
obstructed.
Condensate collects in the
pipe.

Maintenance
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from
the discharge of fluids.
CAUTION
Be sure to use only the recommended components when repairing the
product, and NEVER attempt to modify the product in any way. Failure to
observe these precautions may result in damage to the product or burns
or other injury due to malfunction or the discharge of fluids.
CAUTION
Operational Inspection
A visual inspection of the following items should be done on a daily basis to determine
whether the product is operating properly or has failed. Periodically (at least biannually)
the operation should also be checked by using diagnostic equipment such as a
stethoscope, thermometer, TLV Pocket TrapMan or TLV TrapMan.
If the product should fail, it may cause damage to piping and equipment, resulting in
faulty or low quality products or losses due to steam leakage.
Normal
:
Condensate is discharged continuously, together with flash steam,
and the sound of flow can be heard. If there is very little
condensate, there is almost no sound of flow.
Blocked
(Discharge Impossible)
:
No condensate is discharged. The product is quiet and makes no
noise, and the surface temperature of the product is low.
Blowing
:
Live steam continually flows from the outlet and there is a
continuous metallic sound.
Steam Leakage
:
Live steam is discharged through the trap outlet together with
condensate, accompanied by a high-pitched sound.
(When conducting a visual inspection, flash steam is sometimes mistaken for steam leakage. For this
reason, the use of a steam trap diagnostic instrument [such as TLV TrapMan if appropriate] in
conjunction with the visual inspection is highly recommended.)

Instructions for Plug/Holder Disassembly and Reassembly
The seal on the threaded plugs/holders found on TLV products is formed by a flat metal
gasket. There are various installation orientations for the gaskets, such as horizontal,
diagonal and downward, and the gasket may be pinched in the thread recesses during
assembly.
Instructions for Disassembly and Reassembly
①Remove the plug/holder using a tool
of the specified size (distance across
flats).
②The gasket should not be reused. Be
sure to replace it with a new gasket.
③Clean the gasket surfaces of the
plug/holder and the product body
using a rag and/or cleaning agents,
then check to make sure the
surfaces are not scratched or
deformed.
④Coat both the gasket surface of the
plug/holder and the threads of the
plug/holder with anti-seize, then
press the gasket onto the center of
the gasket surface of the plug/holder,
making sure the anti-seize affixes
the gasket tightly to the plug/holder.
Check to make sure the gasket is
not caught in the recesses of the
threads.
⑤Hold the plug/holder upside down to
make sure that the anti-seize makes
the gasket stick to the plug/holder even when the plug/holder is held upside down.
⑥Screw the plug/holder by hand into the product body while making sure that the
gasket remains tightly affixed to the center of the gasket surface of the plug/holder.
Make sure the entire gasket is making contact with the gasket surface of the
product body. It is important at this point to make sure the gasket is not pinched in
the thread recesses of the plug/holder.
⑦Tighten the plug/holder to the proper torque.
⑧Next, begin the supply of steam and check to make sure there is no leakage from
the part just tightened. If there is leakage, immediately close the inlet valve and, if
there is a bypass valve, take the necessary steps to release any residual pressure.
After the surface of the product cools to room temperature, repeat the procedure
beginning from step 1.

well clear of it, as the jet of condensate or steam could cause burns.
2. Remain in the area the entire time the BD2 valve is in the open position. Before
opening the BD2 valve, grip the BD2 valve seat with a wrench and hold firmly in
place so that it will not rotate when the BD2 valve is loosened. Grip the BD2 valve
with another wrench and slowly loosen. Condensate and steam will discharge from
the blow outlet in a jet stream. Be careful not to loosen the BD2 valve so far that it
becomes removed from the BD2 valve seat. (If the grooved pin becomes damaged,
large quantities of steam will be discharged in a jet stream.)
3. Close the BD2 valve until the flow of fluid completely stops. If the flow of fluid does
not stop, re-open the valve (as in step “2”) to blow out any scale or dirt that may be
caught in the valve. Re-tighten the valve until the flow of fluid stops completely.
