11. Ball ValvesThe FRIALEN ® Ball Valve KH/KHP(see Fig. 28) closes and opens by a1/4 turn of the activating element.The FRIALEN ® Ball Valve KH/KHPis connected to the piping with itsHDPE fusion ends using FRIALEN ®Couplers, Elbows or T-pieces. It issuitable both for selective networkisolation as well as for isolatinghouse service pipings.Fig. 2811.1 AssemblyThe fusion ends are prepared according to the general installation requirements(remove oxide layer/clean). Before starting the fusion process, theFRIALEN ® Ball Valve head KH/KHP must be aligned corresponding to theplanned actuation to guarantee a correct positioning of the activation rod BS.The extendable FRIALEN ® Installation Kit BS has been especially designedfor the technical and geometric demands of the KHP Ball Valve.WARNING!Media identification and closing direction can be marked on the surfacebox using a marking disk.12. Tapping Ball Valves12.1 AssemblyThe preparation of the installationand the fusion process of the tappingball valve AKHP (Fig. 29) is made assaddle component analogue to theFRIALEN ® Pressure Tapping Tee(see Items 5.1 - 5.5).Fig. 2926
INFORMATION:For a leakage-free tapping of pressurised pipings, we recommendthe tapping unit of the company of Hütz + Baumgarten, Remscheid(www.huetz-baumgarten.de). Please ask our Application EngineeringDepartment.13. Transition Fittings13.1 AssemblyWARNING!When removing the PE protectionlid, please ensure that the wire isnot damaged.The general installation instructionsfor the FRIALEN ® SafetyFittings (see Chapters 4.1 - 4.9)are to be observed.13.2 Transition Fittings with steelpipeFig. 30WARNING!In addition, the following items are to be considered:- A shortening of the steel pipe is impermissible because the heat introductionduring fusion has a negative effect on the sealing system.- Fusion of the steel side only by arc welding.- When fusing the steel end it has to be prevented that fusion vapour andfusion beads get into or to the FRIALEN ® Coupler with integrated heatingcoil.27
