Hint!
Statically loaded gaskets in the product-contacting area are generally
not lubricated. To facilitate assembly (better gliding properties and
securing against turning), this type of elastomer seal may, however,
be wetted using a food-grade lubricant.
! Wetting elastomer gaskets is not permitted when they are used in
ATEX applications!
10.8 Removing and Installing the "Shrunk-on” Valve Seat Seal
10.8.1 Removing the Shrunk-on Valve Seat Seal
For information on valve seat seals, see Section 3.3, Page 18
Tools required:
•
O-ring cutter
• Heat-resistant protective gloves
Caution!
Health hazard due to toxic fumes!
The O-ring cutter cuts the seal with a hot metal tip. At temperatures of more
than 300 °C, toxic fumes can be released.
► Avoid directly inhaling the fumes.
Caution!
Risk of injury due to hot and sharp-edged parts!
The O-ring cutter cuts the seal with a hot metal tip. This process heats up
the seal and possibly also metal parts of the valve.
► When removing the valve seat seal always wear heat-resistant protective
gloves.
Carry out the following steps:
1. Place the heated metal tip of the O-ring cutter at right angles on the valve
seat seal to be removed.
2. Cut through the valve seat seal at one point using the O-ring cutter.
! Pay attention not to damage the edge of the radial groove.
