b'MULTI-WAY BALL VALVES - BV509/509A, BV2057, BVL50~L54, SL8142-FZ SERIES1.2.2 Long Term StorageIf valves are to be stored more than one year, they should be prepared in the following manner:a) Remove the packing and apply a preservative to the packing chamber.b) Do not remove the protective end covering.c) Do not store the valves outdoors.1.3 PREPARATIONa) Remove the valve end protection.b) Prior to shipment, a preservative/corrosion inhibitor may have been applied to the inner body of the valve. This preservative/corrosion inhibitor can be removed with a solvent provided the solvent used does not affect the seats/seals used in the valve.c) The inside of the valve should be inspected and blown out with compressed air. Adjacent piping must be clean and free from debris to prevent damage to the valve.d) To prevent valve distortion, inefficient operation or early maintenance problems, support piping on each side of the valve.e) Make sure the valve is positioned such that there is sufficient space so that the hand wheel is easily and safely reached and there is enough clearance for the stem when the valve is open.f) Install the valve according to the flow indicator on the valve body where applicable.2 . 0 I N S T A L L A T I O NFor flange end valve, stud nuts should be tightened in an opposing criss-cross pattern in equal increments to ensure even gasket compression. Refer Appendix A.The following procedure is required to be followed for correct installation.a)Before installation confirm the marking (rating, size and material) on the valve body and nameplate.Ensure the valve is suitable for the service which it is being used. b)Body bolts and nuts on valve shall be checked and retightened if necessary in case loosened during installation.c)Remove valve end protectors and ensure gasket faces are free from damage. Tighten all bolts between mating flanges and valve equally paying careful attention to properly tighten bolts. Ensure you rotate tightening procedure (opposing bolts sequentially) gradually increasing torque. Refer to Appendix Table 3 for tightening sequence.d)Prior to installation of valve, ensure the line is completely flushed to remove any debris as soft seated ball valves are easily damaged. Filters or strainers should be installed upstream to protect soft seated valves.6 Flowturn - Installation, Operation and Maintenance Manual'
