BALL VALVES - FS900 SERIES
DURING 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 valve’s 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.

This manual describes the methods of installation and maintenance for floating ball valves. The ASME
class or cold working pressure shown indicates the maximum rating of the body however, seats & seals
down rate the pressure and temperature. See section 5 for pressure/temperature chart.
1.1 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.
1.2 STORAGE
1.2.1 Temporary Storage
If 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.
1.2.2 Long Term Storage
If valves are to be stored more than one year, they should be prepared in the following manner:
a) Remove the packing and apply a preservative to the packing chamber.
b) Do not remove the protective end covering.
c) Do not store the valves outdoors.
