b'MULTI-WAY BALL VALVES - BV509/509A, BV2057, BVL50~L54, SL8142-FZ SERIESDURING OPERATION TAKE INTO ACCOUNT THE FOLLOWING WARNINGS:a- Graphite/Graphoil packing and body gasket is very brittle, any impacting, twisting or bending should be avoided.b- The valves internal parts such as ball, stem, seats, seals, gaskets shall be handled with care avoiding scratches or surface damage.c- All tools and equipment for handling internal critical sealing parts shall be soft coated.d- Valves can be fitted with gaskets or seals in PTFE, Buna, Viton, etc., hence high temperatures will damage sealing components.e- Never part open valve, valve must be full open of full closed to avoid seal damage.For all operations make reference to position number on part list of the applicable drawing listed.1 . 0 S C O P EThis manual describes the methods of installation and maintenance for multi-way ball valves, which are designed to fit between ANSI Class 150, Class 300 PN10, PN16, PN40 flanges or with buttweld ends or with screwed ends. Multi-way valves are generally not firesafe and not for throttling use.The operating temperature is within -29C to 200C for PTFE, RTFE or TFM1600 seat and sealing. Other seat and sealing operating temperature shall be checked with APV.The nominal pressure (PN) rating or ASME rating indicates the body pressure/temperature however, the seats and seals reduce the temperature and pressure rating. Refer to Appendix G.1.1 ENVIRONMENTAL CONSIDERATIONSAccording to ISO 14000 regulations and the environmental policy of APV, the recyclability of the components that form part of APV valves is as follows:Recyclable components:Metal parts, PTFE (hard), plastic plug (low-density polyethylene).Non-recyclable components:PTFE mixed with other compounds (glass-fiber, graphite, etc.), nylon, graphite and graphite mixed with metal.1.2 STORAGE1.2.1 Temporary StorageIf valves are to be stored before installation, the following should be observed:a) Keep the valves wrapped and protected as shipped from the manufacturer.b) Do not remove the protective end covering until the valve is ready for installation. This will reduce the possibility of foreign material damaging the internal valve components.c) Valves stored outdoors should be positioned such that water does not accumulate in the valve body.Flowturn - Installation, Operation and Maintenance Manual 5'
