1. Specifications
* For installation posture, see 3 of “5.2 Precaution for installation“ .
*Install a strainer (recommended: 80 mesh) at the inlet side to protect TSF-13 from scale or other foreign
substances. Due to the double-port structure, foreign substances stuck on the valve and valve seat may cause
significant steam leakage.
Caution
1. Depending on application, specification of the product shall be selected. Refer
to Technical material, e.g. Operating instruction, Technical guidebook, and
drawing, and select suitable specification. Regarding technical material like
drawing, contact our sales office.
2. Please confirm that the indications on the product correspond with the
specifications of the ordered product model before use.

3. Operation
At start-up, since the ⑮float is down, the ⑦valve set is closed. In this state, air in the system and
piping is discharged out through the ⑯air vent which is opened.
When condensate flows into the product, the ⑮float lifts up and opens the ⑦valve set, and then
discharges condensate. Air is continuously discharged out from the ⑯air vent. When steam flows into
the product, internal pressure of the ⑯air vent rises by steam temperature, and the ⑯air vent closes.
According to the amount of condensate inflow, the ⑮float position moves up and down changing the
opening degree of the ⑦valve set, and thus condensate is continuously discharged.

4 ■EPDT-348a■
4. Maximum Continuous Discharge Capacity
1. Discharging capacity of the steam trap differs by working differential pressure, that is, difference
between inlet pressure and outlet pressure (back pressure). In selecting discharge capacity,
consider outlet pressure. If inlet pressure is 0.5 MPa and outlet pressure is 0.2 MPa, discharge
capacity is of working differential pressure of 0.3 MPa.
2. The discharge capacity shown in the charts below is the maximum value. In designing a system, select a
steam trap with a sufficient safety factor (at least twice). That is, for example, if a discharge capacity of 2000
kg/h is required, select a steam trap capable of discharging more than 4000 kg/h (maximum discharge).

If the product is installed close
to a regulating valve, make
sure to install the product at
the inlet side of the regulating
valve.
To discharge condensate from
the steam main, be sure to
install the product on piping
taken from the lower part of
drip leg.
Install the product below a
device which generates
condensate.

Description

Install the products for each
device independently.
The diameter of collecting pipe
shall be more than summation
of sectional areas of discharge
pipes.
In addition, install check valves
for back flow prevention.
For condensate recovery,
connect the discharge pipe to
the upper part of collecting
pipe.
For traps of different pressure
lines, install collecting pipes
individually for each pressure.
In addition, install check valves
for back flow prevention.
* Re-evaporated steam in high
pressure line increases the back
pressure of low pressure trap.
End portion of discharge pipe
shall be off the water surface in
the pit.
* If the discharge pipe is in contact
with the water, it absorbs dirty
water in the pit and causes
malfunction of the product.
Provide a by-pass line around
the product, and install stop
valves at the outlet side of the
product.

7 ■EPDT-348a■
5.2 Precaution for installation
Warning
1. In order to discharge condensate to the atmosphere, lead the outlet to a safe place where there is no
possibility of physical damage even if condensate blows out.
* There are risks of scalding or injury when the condensate blows out.
Caution
1. Before connecting the product to piping, remove foreign substances and scale from the piping.
* Failure to follow this notice may prevent the product from functioning properly.
* To plumb the product, be careful to keep seal materials from entering into the product.
2. To install the product, check the direction of the product so that the fluid flowing and the arrow mark on
the product are in the same direction.
* Setting the product in wrong directions prevents it from functioning properly.
3. The mounting position of the product is horizontal piping. Do not tilt the product during use.
* Do not install in vertical piping．
* Wrong posture hampers proper operation.
* Allowable tilt from horizontal line is within ±5°.
* Support the product cover when it is necessary.
4. Make sure to support the piping immovably.
* If an excessive piping stress is applied, there are cases when the product will not open or close.
5. Do not disassemble the product unless it is necessary.
*Unnecessary disassembly may prevent the product from functioning properly.

8 ■EPDT-348a■
6. Secure enough space for maintenance, inspections and repair as shown below.
* Failure to follow this notice prevents maintenance, inspection and repair.
*Common to 40A and 50A
7. Slope the piping and place the product at as a low position as possible in order to make condensate
flow into the product by its own weight.
8. To install the product in a main steam pipe, provide a drip leg at the inlet side of the product.
9. Install a strainer (mesh size of 80 or more is recommended) at the inlet side of the product.
10. Install the product in a way it is not subjected to the shock of water hammer. Do not install a quick
operating valve before and/or after the product.
* Failure to follow this notice may result in malfunction due to damage to the ⑮float or ⑯air vent, or may
result in scalds or injury due to blow off when the product is subjected to an excessive shock and damaged.
11. Install a bypass line.
* The system has to stop operation while inspection and maintenance of the product if the bypass line is not
installed.
12. Pipe size of the outlet side of the product should be large enough so that the discharged condensate flows
without any resistance.
* If the outlet piping causes resistance, the specified discharge amount may not be obtained.

9 ■EPDT-348a■
6. Operating Procedure
6.1 Precaution for operating procedure
Warning

8.1 What is SLR
If you need the product with ⑱Steam Lock Release (SLR), please let us know when you purchase. It
cannot be attached to the standard product later.
Steam locking occurs when the pipe to the trap is filled with steam and the steam prevents
condensate from flowing into the trap. The ⑱SLR bypasses the ⑯Air Vent to discharge steam and
prevent steam locking.

8.3 How to use SLR
(１) To open the ⑯Air Vent
Turn the slotted head of ⑱SLR in the direction of A by a flathead screwdriver. The more you screw in, the
more the ⑯Air Vent opens. However, do not screw in beyond E ring stopper. If you turn it any further, the
⑯Air Vent may be damaged.
(2) To use the ⑯Air Vent normally
Turn the slotted head of ⑱SLR in the direction of B until it stops. At the time of product shipment, the ⑱
SLR is in this state.
※Be careful not to strip the slotted head when you turn it.
※Do not turn Gland Holder or Gland Bolt, or outside leakage may occur.
