8. Spigot Saddles8.1 <strong>Assembly</strong>The preparation of the installationand the fusion process is made analogueto the FRIALEN ® PressureTapping Tee (see 5.1 - 5.4).WARNING!Fig. 23The tapping is made with commercially available tapping units in an unpressurisedstate with or under pressure using shut-off valves.We recommend the tapping unit of the company of Hütz + Baumgarten,Remscheid (www.huetz-baumgarten.de), especially designed for this purpose.Please ask our FRIALEN ® Application Engineering Department.The manufacturer’s installation instructions are to be observed.9. Reinforcement and repair saddles9.1 <strong>Assembly</strong>In case of selective pipe damages,the damaged area can be closedwith a plug and then fused with thereinforcement and repair saddle.Each half shell is to be fused separately.The preparation of the installationand the fusion process of the individualhalf shells is made analogueto the FRIALEN ® Pressure TappingTee (see 5.1 - 5.5).Fig. 24WARNING!Care must be taken to ensure that during assembly the damaged ordeformed point on the pipeline lies in the centre of the heating element.22
10. FRIALOC PE shut-off valve10.1 Areas of applicationFRIALOC PE shut-off valves made ofPE 100 can be used in water supplysystems according to DVGW (GermanTechnical and Scientific Associationfor Gas and Water) W400-2and EN 805 with a maximum componentpart operating pressure PFA(PN) of 16 bar.FRIALOC PE shut-off valves meetthe requirements on componentparts for use in water supply systemsaccording to DIN EN 12201-4and DVGW VP645.Fig. 25The approval for use in gas supply according to DVGW G472 and EN 12207-2 is being prepared (status: 01/08).For the planned installation of FRIALOC PE shut-off valves into other pipingsystems, please state the flow medium and the operating conditions (pressure,temperature, planned period of use…) to clarify if our application technologyis suitable.The preferred type of installation of FRIALOC PE shut-off valves is a material-homogeneousinstallation in PE piping systems using FRIALEN ® safety fittings.Using the fusion flanges FRIALEN ® EFL, installation into pipings madeof other materials is also possible. When using mechanical joining methods,e.g. FRIAGRIP, the specific installation instructions are to be observed.FRIALOC PE shut-off valves can be both buried or installed in systemsabove ground.Information:For up-to-date and detailed information on FRIALOC PE shut-off valves,please see the technical datasheets available on the Internet(www.frialen.com).23
