1.2 Proper application
The non-return valve is used in the food and beverage industry and in the pharmaceutical
and chemical industry. The valve can be used to prevent the backflow of medium or to
disable one flow direction.
Applicable and generally recognized safety rules must be followed during assembly and
disassembly, in operation and during maintenance.
The instructions in the operating manual must be followed without exception.
1.3 Misuse
Misuse is:
•Application in different operating conditions as intended for the specific type.
•Installation, operation and maintenance by unqualified staff.
•Any unauthorized modification of the valve or a valve component.
•On-observance of the operating instructions.
Any misuse will automatically lead to a loss of right to claim under guarantee as well as
any liability.

Replacing the sealing rings:
•Loosen the grooved union nut and take the connecting piece out of the housing.
•Remove the guide star (5) and spring (4) from the valve rod.
Take the valve rod with valve disk (6) out of the housing.
•For divided valve disks unscrew the bottom part of the valve cone and change the
O-Ring (3). Use screw locking fluid e.g. Loctite 221
•If the valve disks are not divided, take the O-ring out of the disk groove with a dig-
hook.
•Change O-ring (1).
