GRW/GRL Installation & Operation Manual
1 Storage & 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 77°F (25°C), above 32°F (0°C) preferable below 59°F
(15°C).
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.
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.
