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.
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.
The operator has to make sure that:
•
The valve/component is operated properly and only in functional condition.
•
The legal requirements are kept during operation and maintenance.
•
Only sufficiently qualified and authorized staff maintain the valve/component.
•
The staff responsible for operation and maintenance know and obey the
operating instructions and in particular the safety advice.
•
The safety and warning signs remain on the valve/component and are
always legible.
