b'WAFER PATTERN CHECK VALVES - ASG & AGW STYLES A F E T Y I N F O R M A T I O N The following general safety information should be taken into account in addition to the specific warnings and cautions specified in this manual. They are recommended precautions that must be understood and applied during operation and maintenance of the equipment covered in this I.O.M.To avoid injury, never attempt disassembly while there are pressures either upstream or downstream. Even when replacing gaskets or packings, caution is necessary to avoid possible injury. Disassemble with caution in the event all pressures are not relieved.To prevent valve bending, damage, inefficient operation, or early maintenance problems, support piping on each side of the valve. A valve is a pressurised mechanism containing fluids under pressure and consequently should be handled with appropriate care. Valve surface temperature may be dangerously too hot or too cold for skin contact. Upon disassembly, attention should be paid to the possibility of releasing dangerous and or ignitable accumulated fluids. Ensure adequate ventilation is available for service.This manual provides instructions for storing, general servicing, installation and removal of valves.APV and its resellers refuse any liability for damage to people, property or plant as well as loss of production and loss of income under any circumstances but especially if caused by: Incorrect installation or utilisation of the valve or if the valve installed is not fit for intended purpose.It is the sole responsibility of the user to ensure the valve type and materials are correctly specified.DURING OPERATION TAKE INTO ACCOUNT THE FOLLOWING WARNINGS:a- The valves internal parts (disc/stem/hinge pin/seats/gaskets/seals, etc.) shall be handled with care avoiding scratches or surface damage.b- All tools and equipment for handling the internal parts shall be soft coated, or else take care.c- Valves can be fitted with gaskets or seals in PTFE, Buna, Viton, etc., hence high temperatures and some cleaning fluids may damage sealing components.For all operations make reference to position number on part list of the applicable drawing.Australian Pipeline Valve - Installation, Operation and Maintenance Manual 3'
