  • Page 3: Intended Use

    1 Intended use After the installation into a pipeline, butterfly valves are only intended for stopping or allowing media to pass within the range of the permitted operating conditions (temperature and pressure limit "PN" labeling on the valve, unless stated otherwise). These valves are preferably intended for liquid media, such as drinking water or gas.

  • Page 4: Special Risks

    Do not operate a valve whose permissible component operating pressure ("Ps") and maxi- mum permissible operating temperature ("Ts") are not sufficient for the operating condition. The area of application is marked on the valve. Within the permissible operating temperatures, there is a risk of injury when working on the piping components at temperatures below 10 °...

  • Page 5: Transport And Storage

    3 Transport and storage All valves must be carefully transported and stored. The valves are fully enameled or powder-coated. The coatings are shock-sensitive and must be protected against impact stress. The gaskets are sensitive to light: Unpackaged valves may only be exposed to bright daylight or ultraviolet light for a very short time.

  • Page 6: Pressure Test On The Pipeline

    4 Pressure test on the pipeline  New installed pipelines should be carefully flushed first to wash out all foreign bodies.  Valve open: The test pressure may not exceed the value 1.5 x PN (see valve markings).  Valve closed: The test pressure may not exceed the value 1.1 x PN (see valve markings). 5 Installation into the pipeline 5.1 General information Only original spare parts from the manufacturer may be installed.

Check the exact location of the profile sealing (9) in the retaining groove.

  • Page 16: Adjusting The Retaining Ring

    In case of leakage, adjust retaining ring in closed position. To do this loosen grub screws (23) and tighten countersunk screws (27) with permissible torque. After this operation, turn the grub screws (23) clockwise to make contact with the surface of the butterfly disc (3). 10.3 Adjusting the retaining ring The retaining ring (4) can be adjusted in the CLOSED position of the butterfly valve.
