Packing List

Check the packing list against the materials received. Lists
describing the valve and accessories are included in each
shipping container and general assembly drawing as applicable.

WARNING

Never lift the valve or valve package by the actuator, positioner,
limit switch or their piping. When lifting a valve, be aware that
the center of gravity may be above the lifting point. Therefore,
support must be given to prevent the valve from rotating. Failure
to do so can cause serious injury to personnel and damage to the
valve and nearby equipment.

Contact your shipper immediately if there is shipping damage.
Should any problem arise, contact your Bray representative.
