 SERIES 60 BUTTERFLY VALVES

INSTALLATION AND OPERATION MANUAL

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.

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.

Before installation these instructions must be fully read and understood

IMPORTANT

Before valves are installed or used the following 
actions are recommended.
1.  Valves/parts have to be inspected and 

thoroughly cleaned if required.

2.  Elastomer 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. Do not fasten lifting devices 
around the valve operating shaft, actuator 
or through the valve waterway. The valve 
should be lifted with chains or slings which 
are fastened to rods or bolts which go through 
the bolt holes in the body flanges. 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 cannot be 
guaranteed if third party spare parts are used.

VCIOM-03761-EN 15/08

Recommendations

1.  Temperature: storage temperature below 

25°C (77°F), above 0°C (32°F)  preferable 
below 15°C (59°F)

2.  Humidity: storage conditions should be such 

that condensation does not occur. Store in 
a dry environment. Maximum 50% relative 
humidity.

3.  Light: valve elastomers 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.
