Replacing the seals
✗
Replace defective seals.
Always replace the hous ing O-rings to ensure the
tightness of the valve. Always use original spare parts.
CAUTION
When the V-Ring is re mov ed with a scriber, the scriber
can slip off. There is danger of injury. Therefore grip the
valve disk in a vice fitted with pro tec t ed jaws. Also
unscrew the curved end of the scriber.
• Insert the scriber into the V-ring and lever it out.
Use the insertion tool to mount the new V-ring.
✗
Do not grease the V-ring before inserting it.
We recommend using water with household washing-
up liquid (1 drop/1 l) as an aid to inserting V-rings. In
order to prevent oxida tion from infiltration prepare
the liquid solution in a ceramic, plastic or stainless
steel container.
Before inserting the V-ring wet it on the back (side not in
contact with the product). Take care that there is no
water in the V-ring groove in the valve disk.
CAUTION
• Observe the required installation position of the
V-ring (see ill.).
• Insert the V-ring (see ill.).
• Using the V-ring inser tion tool press the V-ring into
the groove at several opposite places along the cir-
cumference.
• Insert the V-ring evenly into position.
• Replace all the other seals correspondingly
marked in the spare parts drawing.
✗
Used seals must not be refitted, since this
would adversely affect the sealing function.
