KEYSTONE
OPTISEAL F14/16 - 15/17 AND BREWSEAL BUTTERFLY VALVES
INSTALLATION AND MAINTENANCE INSTRUCTIONS
1 STORAGE AND HANDLING
1.1 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.
1.1.1 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.
Recommendations
1. Temperature: storage temperature below
25°C, above 0°C preferable below 15°C.
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.
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.
When the valve is used in an end-of-line function,
PED Cat-I applications are allowed only. For
other categories, please contact the factory.
VCIOM-00747-EN 15/05
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.
1.2 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 vibration) during transport.
Any flange protection caps need 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/-
hydraulic actuator or other instrumentation.
2 SPARE PARTS
Only original Keystone spare parts are
allowed to be used. Safe operation can not be
guaranteed if third party spare parts are used.
4. Ozone: storage rooms should not
contain any equipment generating ozone.
E.g. lamps, electric motors.
