ES-009/009-FS

Series 009 and 009-FS

Reduced Pressure Zone Assemblies

Size:

⁄4" – 2"

Series 009 and 009-FS Reduced Pressure Zone Assemblies are

designed to protect potable water supplies in accordance with

national plumbing codes and water authority requirements. This

series is designed to protect drinking water supplies from dan-

gerous cross-connections in accordance with national plumbing

codes and water authority requirements for non-potable service

applications such as irrigation, fireline, or industrial processing.

The series features two in-line, independent check valves, captured

springs, and replaceable check seats with an intermediate relief

valve. Its compact modular design facilitates easy maintenance and

assembly access. Sizes

⁄4" to 1" shutoffs have tee handles.

Series 009-FS assemblies of sizes ½" to 2" include an integrat-

ed flood sensor to detect excessive water discharges from the

relief valve. When activated through an add-on sensor connec-

tion kit, the flood sensor relays a signal that triggers notification

to qualified service personnel who can take corrective action,

thus avoiding the possibility of ruinous flooding and costly dam-

age. The add-on sensor connection kit is available for both

building management systems, or BMS, and cellular communi-

cation. (For more information, refer to Installation, Maintenance,

and Repair Manual, Series 009-FS and LF009-FS.)
