Then use both palms to press the valve seat seal in place in the radial groove.

When pressing in, pay attention to the “engaging” of the valve seat seal into

the radial groove. The generated clicking sound is proof of correct installation.

After fitting a new TEFASEP gold valve seat seal, it could be that the valve

might not be leak-proof yet. Only after the first CIP or SIP cleaning (see
Section 9.1, Page 39) the valve seat seal will adjust itself optimally to the
sealing surfaces and will ensure perfect sealing up to the maximum closing
pressure or vacuum.

Fig.52

The valve seat seal is still too rigid and cannot be mounted?

Heat the valve seat seal again as described in the first step.

When mounting the valve seat seal, the seal does not "click" into place any

more?

The valve seat seal has been overheated and can no longer be used.

Repeat the operation with a new valve seat seal.

Observe the data specified for heating the valve seat seal.

The valve seat seal has been removed.
