2.1 Intended use
The VARIVENT
®
FRS valve is designed for use with powdery media as well as
CIP and drying processes. The powder medium is conveyed through the process
housing with the valve closed. By means of flush bores, preferably sterile
compressed air that flows through a gap in the valve disk to the process housing,
can be applied to the valve seat. Thanks to this pressurisation any collection of
powder at the valve seat can be avoided.
When the valve is open, cleaning medium can be fed via the single-spout CIP
housing. After the CIP cleaning has been carried out, the valve can be dried in
open valve position with hot air or steam (see “Technical data” (page 21).
The FRS valve is used for opening and closing pipeline sections.
Hint!
The manufacturer will not accept any liability for damage resulting
from any use of the valve which is not in accordance with the
designated use of the valve. The risk of such misuse lies entirely with
the operator of the facility.
