STORAGE AND LIFTING
Check and document any damages in the valve packages
or valves. Contact the transportation company in case of
damage. When new or unused valves are removed from
operation or stored for a long period of time, the following
procedures should be complied with:
1. Prior to storage, thoroughly drain valves of all water.
2. Indoor storage is required. For unfavourable
environment, cover the equipment with protective
tarpaulin that will allow proper air circulation
3. Protect the equipment from temperature and humidity
extremes and exposure to excessive dust, moisture,
vibration and sunlight.
4. It is preferred to store valves in the open position.
5. Avoid dirt and/or moisture contamination of the stem
(threaded rod).
6. Ensure pneumatic cylinder actuators have appropriate
pipe plugs installed in the respective supply ports to
prevent contamination of the cylinders.
7. Protect valve sleeves from heat, sunlight and exposure to
ozone.
8. Cover the flange openings.
9. Do not store any objects on top of the rubber sleeves.
10. Follow the actuator instructions for storage.
11. Before start-up clean the valve.
When storing used valves, wash the valve with fresh water
and follow the steps above. For storage periods greater than
36 months, please contact Valmet as the rubber parts need to
be changed before use.
Lifting equipment must be used for valves weighing over
25kg.
Lift the valves securely from the body (part 1 in Figure 1) or
actuator (part 3 in Figure 2) and use existing lifting eyes when
available. When lifting eyes are not available, use soft straps to
lift valve.
