4. Instructions and precautions before
installation and operation
Present instructions should be carefully reviewed before mounting and operation of
Ballomax® ball valves:
• The entire system should be depressurized and emptied before any type of
disassembly, replacement or repair of a single element, regardless of whether
the elements are damaged or not.
• Control that the valve is suitable and approved for the used media and the
desired application. The valve is not suitable for steam! Here a valve suitable for
high temperatures is to be used.
• Operate the valve, if possible, to ensure that the valve is not defective from
storage or transportation.
• If the valve is used as an end valve in the pipeline, there has to be installed a
pressure tight ending or blind ange after the valve and the valve is to be left in
the open position (Figure 4).
• In order to ensure safe operation the manual gear or actuator cannot be
removed or dismantled, without special precautions are taken, if the valve is
under pressure and/or there is a ow.
• BROEN recommends, that the valve is installed in the pipeline with minimal
vibrations. In the installation it is recommended to avoid stress and to relieve
the valve for exposed longitudinally pressure and tensile load.
