• The protection must be restored following the instruction indicated from APV in accordance with the
painting cycle used.
• Without any gate 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.
• After cleaning and lubrication the gate must be operated (close/open complete stroke).
• The gate 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.
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:

2.1 VALVE PREPARATION
a- Remove the ends protectors and check accurately the status of the valve as indicated in point 1.2.
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- Do not operate the valve until the following procedures have been fully applied:
• Clean internal conduits.
• After cleaning the gate must be operated (one complete stroke).
• During installation the gate must be kept in the fully open position.

API6D THROUGH CONDUIT EXPANDING GATE VALVE - AP400-405 SERIES
Note
If the valve and actuator are delivered separately, APV recommends utilising a
qualified technician to mount the actuator to the valve, make all necessary
adjustments, fully test and debugged the unit before installing the valve in the
pipeline.
