2 PIECE BODY BALL VALVES - FS660 SERIES
Australian Pipeline Valve - Installation, Operation and Maintenance Manual
5
DURING OPERATION TAKE INTO ACCOUNT THE FOLLOWING WARNINGS:
• Graphite/Graphoil packing and body gasket is very brittle, any impacting, twisting or bending should
be avoided.
• The valve’s internal parts such as ball, stem, seats, seals, gaskets shall be handled with care avoiding
scratches or surface damage.
• All tools and equipment for handling internal critical sealing parts shall be soft coated.
• Valves can be fitted with gaskets or seals in PTFE, Buna, Viton, etc., hence high temperatures will
damage sealing components.
• Never part open valve. Valve must be full open of full closed to avoid seal damage.
• APV firesafe ball valves are provided with anti-static devices for ball-stem-body. When service
conditions require electrical continuity to prevent static discharge, the user is responsible for
specifying static grounding.
• When ball valves are to be utilised on liquids with very high velocity, check with the valve distributor
or manufacturer for appropriate advice to minimise the possibility of seat deformation, especially when
they are highly pressurised on a high-temperature line.
• Ball valves are generally not recommended for throttling service, where both the fluid flow and the
leading edge of the ball can damage or deform the resilient ball seats causing leakage. High fluid
velocity or the presence of solid particles in suspension will further reduce seat life in throttling
applications.
• Do not open the bonnet or cap when bearing pressure. Valve is not equipped with pressure access
device. User should check it by other method through its piping system.
• Do not touch the surface of a valve at high temperature.
• Not allowed for unstable fluid unless otherwise specified.
• Lock design on the handle is to avoid the valve being operated by non-related people and is an option
upon request.
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, which are
designed to fit between ANSI Class 150, Class 300 and Class 600 flanges or with buttweld ends.
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-fibre, graphite, etc.), nylon,
graphite and graphite mixed with metal.
