NOTE: - Coat all threaded portions and valve seat gasket with anti-seize.
- Tightening torques for metal and rubber valve seats are identical.
- If drawings or other special documentation were supplied for the product, any torque
given there takes precedence over values shown here.
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
1. Remove the plug/holder using a tool of the specified size (distance across flats).
2. The gasket should not be reused. Be sure to replace it with a new gasket.
3. 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.
4. 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.
5. 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.
6. 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.
7. Tighten the plug/holder to the proper torque.
8. Next, begin the supply of air/gas 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.
