DURING OPERATION BEAR IN MIND THE FOLLOWING WARNINGS:
a- The graphoil packing and body gasket is very brittle: any twisting or bending shall be avoided.
b- The internal parts of valves (ball, stem, seats) shall be handled with care avoiding scratches or surface
damage.
c- All tools and equipment for handling and supporting internal critical sealing parts shall be coated with
soft materials.
d- Seats & seals usually include Viton, Devlon & Teflon, hence high temperatures and some chemicals will
damage sealing components.
e- Never part open valve, valve must be fully open of fully closed or else the seats will be damaged.

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 can then damage the seat.
• After cleaning, 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.
