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
Remove the plug/holder using a tool of the specified size
(distance across flats).
The gasket should not be reused. Be sure to replace it with a
new gasket.
Clean 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.
Coat 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.
Hold 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.
Screw 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.
Tighten the plug/holder to the proper torque.
Next, 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
11. Troubleshooting
If the expected performance is unachievable after installation of the steam trap, read chapters 5
and 6 again and check the following points to take appropriate corrective measures.
