Storage
Valves Delivered by NUTRON
After valves are assembled and tested, they are placed in the full open position, flange seal surfaces and
bores are greased and end protectors are installed. This will provide adequate protection for indoor
storage. Extended outdoor storage or storage in particularly harsh environments (i.e. an uncovered
marine atmosphere) requires periodic inspection and the addition of a corrosion inhibitor. Contact your
NUTRON representative for extended storage guidelines. Valves should only be stored in the fully open
or fully closed position to prevent seat distortion.
Lifting and Handling Guidelines
Always use suitable lifting equipment and supports.
Make sure that devices (including but not limited to
lifting cranes, chains, or slings) are in good condition
and properly rated for the weight of the valve plus
any mounted actuation components before lifting
loads.
Ensure that staff who take part in the lifting process
have sufficient training for the job. Participate in a
pre-job safety meeting or lift plan prior to any
operation. Establish red zones (no-go zones) prior to
the lift.
Always secure the lifting to the valve body, never to
the actuator; otherwise, the stem/shaft may be
damaged.
Before attaching the load, be aware of the weight of
the load to be lifted and locate the center of gravity to prepare for how the load will behave and to
ensure balanced lifting. Lift the valve in the position in which is it to be installed. Lift and move the load
at an even pace to avoid swaying. Never leave the load suspended in mid-air.
Make sure that the valve and actuator (if equipped) are correctly in place and secured prior to detaching
the supports. Make sure the load does not fall over when you undo the supports.
Refer to the packing list or product catalogue for specific valve weight
Refer to detail lifting drawings (available upon request) for specific weight and center of gravity.
