SECTION III
INSPECTION
1. Before installation of the valve into the piping system, visually inspect the valve to determine
if any damage has occurred during shipping. Particularly, inspect the actuator, shaft, valve
interior, valve body and flanges. For proper operation of the valves, the seat and disc seal
must be undamaged and free of foreign material. If other than superficial damage is
discovered, contact Flowserve immediately, indicating the location and extent of the damage
found.
2. If it is necessary to clean the valve, use a soft cloth and mineral spirits, or an equivalent
solvent. All rust preventive should be removed before installing your valve.
SECTION IV
TOOL REQUIREMENT
There are no special tools required for installation and maintenance that are not commercially available.
Any lifting devices used to move the valve into a desired position shall be of sufficient size to support the
weight of the valve and actuator assembly. Nylon slings secured around the valve bearing areas are
recommended to reduce the possibility of mechanical damage occurring to the valve body and actuator.
The assembly should never be lifted by the actuator. (Fig.2)
WARNING
NEVER pass a lifting device through the valve port or severe damage may
occur.
