Installing the Valve in the Pipeline
WARNING
The edges of a rotating disc have a shearing effect that may result in personal injury. To help prevent such injury, stay clear
of the disc edges when rotating the disc (key 3, figure 14).
CAUTION
Damage to the disc will occur if any pipe flanges or piping connected to the valve interfere with the disc rotation path. If the
piping flange has a smaller inner diameter than what is specified for schedule 80 piping, measure carefully to be certain the
disc rotates without interference before putting the valve into operation.
CAUTION
Damage to the disc (key 3) sealing surfaces may occur if the disc is not closed when the valve is being removed from the
pipeline. If necessary, use a temporary pressure source on the actuator to retain the disc in the closed position while
removing the valve from the pipeline.
