1 . 0 P R E S E R V AT I O N & S T O R A G E 1.1 STORAGE a- If storage in the field for a long time before installation is necessary, it is suggested to put valves in a dry and/or covered place. In this case the packaging and end covers integrity is especially important. b- All the valves are supplied with special plastic ends to cover and protect the internal parts. We recommend you do not remove them during storage period. c- Valves should be left in the open position (unless actuated and set fail closed). 1.2 PERIODIC MAINTENANCE DURING STORAGE In case of extended storage, the valves must be inspected and maintained as follows:- • External surfaces must be inspected to ensure no damage to flange faces, paint finish etc. In case of the presence of rust and/or damaged painting, the area must be cleaned by brushing, degreasing & repainting. • The protection must be restored following the instruction indicated from APV in accordance with the painting cycle used. • Without any ball movement, the internal surface of the valves must be inspected to check the complete absence of dust, rust, foreign matters and the integrity of lubricant coat. If not satisfactory then clean and lubricate the internal part using a nebulised lubricant. Do not leave any lubricant on the seat itself or else the seat may attract debris which in turn could damage the seat. • After cleaning and lubrication the ball must be operated (close/open complete stroke). • The ball must be kept in the full open position during installation. • The end of the valve must be protected using the same end covers. • We recommend you tropicalise bore and ends of valves if stored in humid or salt air environment. Grease bore with valve full open so no grease is applied to soft seat inserts. 1.3 ENVIRONMENTAL CONSIDERATIONS According 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.
