the disc position indicator provides avisual indication of the disc locationduring operation or shut down. The745’s top cover is drilled and tappedfor installation of the indicator.

The new 745BF swing checkprovides a drilled and tappedlocation at the bottom of the valvefor installation of a backflow device.Manually operated, this actuator is usedwhen backflow, pump priming, linedraining or system tests are required.This option can be factory installed or

added in the field.

The new 745BFPI swing checkprovides both of the above options.Each device can be installed at the time

of purchase or added to the valve in thefield. A proximity switch is available uponorder of the Model 745PS (not pictured).
