Valves, fittings and pipes delivered by Praher Plastics Austria GmbH are developed and produced according to
international and national standards. Our products have to be exclusively used in the appropriate applications fields. In
this regard, the technical data sheet (pressure-loss-diagram) as well as the operation manual (correct installation,
dismounting) and technical regulations published by the plastics industry as well as chemical resistance lists must be
complied with. Modifications on the product realized on a stand-alone basis are the responsibility and the risk of the
plant manufacturer. Information regarding certificates and eligibility for certifications can be found in the manufacturer's
declaration. Declarations of conformity for the corresponding valves are available according to the pressure equipment
directive.
Leak and function tests have to be carried out before commissioning. After the pressure test, all nuts and screws of the
entire pipe system must be retightened in a depressurized state.
We recommend a maintenance service (testing of functionality and tightness) and careful visual inspection in regular
maintenance intervals minimum once a year, whereas with highly aggressive media, strong vibrations and significant
variations of temperature, the intervals should be shortened. Seals must be considered as wear materials and must be
lubricated and/or changed regularly. Valves that are kept permanently in the same position should be operated 1-2x a
year to check full functionality and tightness.
With unfiltered media we recommend the installation of line strainers.
Before returning the product, we kindly ask you to inform our representation in your country. In order to make a warranty
claim, it is necessary to demonstrate that a test of functionality and tightness has been carried out.
Further information as well as above mentioned information sheets can be provided by our representation in your country
or under www.praher-plastics.com.
Our products are improved continuously in regards to technical progress and further development. Thus, we reserve the
right to implement changes and improvements without notice.
