1.1 Protection
Keystone butterfly valves are delivered with
protection in accordance with the Keystone
engineering instructions, to protect the valve
from damage. wrapping and/or covers should
be left in place until installation of the valve.
1.2 storage
when valves are to be stored for some time
(2 months or more) before being fitted, storage
should be in the original delivery crates or
cases.
1.2.1 storage conditions
the valves should be stored off the ground in a
clean, dry indoor area.
Protect the valve from temperature and
humidity extremes, and exposure to excessive
dust, moisture, vibration, deformations,
sunlight and ozone.
intended valve use
the valve is intended to be used only in
applications within the pressure/temperature
limits indicated in the P/t diagram of the
product manual.
the CompoSeal wafer butterfly valve is
designed for wafer use only. no dead end
service!
ensure that valve materials are compatible with
the pipeline fluid.
1.3 Handling
to prevent damage during handling, the valves
should be lifted by hand or using appropriate
lifting equipment. the valves should be
protected from external events e.g. bumps,
hitting and vibrations during transport. Any
flange protection needs to be removed before
the valve is mounted in the pipeline. Lift the
valve with great care from the transport
package (crate, pallet). while handling or
installing the valve, ensure that no damage
occurs to the valve, the pneumatic/electrical or
hydraulic actuator or other instruments.
Please read these instructions carefully

Warning
For safety reasons it is important to take the
following precautions before starting to work on
the valve:
1. Personnel making any adjustment to the valves
should utilize suitable equipment. All required
personal protection means should be worn.
2. The line must be depressurized before
installing the valve.
3. Installation and handling of the valves should
only be done by personnel that is trained in all
aspects of manual and mechanical handling
techniques.
4. Misuse of the valve is not allowed. The valve,
handles, actuators and other parts may not be
used as ‘climbing tools’.
5. Ensure that valve pressure/temperature
limitations marked on the valves tag plate
are within the service conditions. The trim
number on the valves tag plate identifies
the valve materials. See Product Manual for
valve specific P/T diagram and trim number
definition.
6. Ensure that valve materials are compatible
with the pipeline fluid.
2.1 visual valve insPection
1. Confirm that the materials of construction
listed on the valve are appropriate for the
service intended and are as specified.
2. Check if valve and actuator are not damaged
during transport or handling.

iMPortant
Before valves are being installed or used the
following actions are recommended.
1. Valves/parts have to be inspected and
thoroughly cleaned if required.
2. Rubber parts need to be greased with silicone
grease if not present anymore.
3. All surfaces in contact with seats have to be
thoroughly cleaned and greased with silicone
grease if stored for more than 5 months.
recommendations
1. temperature: storage temperature below
77°f, above 32°f preferable below 60°f.
2. humidity: storage conditions should be such
that condensation does not occur, store in
a dry environment. maximal 50% relative
humidity.
3. Light: valve rubbers should be protected
from light, in particular direct sunlight or
strong artificial light with high ultra violet.
4. ozone: storage rooms should not
contain any equipment generating ozone.
e.g. lamps, electric motors.
