Specification Temperature- Pressure <br /> The reduced pressure zone assembly shall consist of two Maximum working pressure 175 psi (12.1 bar) <br /> independently operating, spring loaded, "Y" pattern check Hydrostatic test pressure 350 psi (24.1 bar) <br /> valves and one hydraulically dependent differential relief valve. Temperature range 320F to 140OF(0°C to 60°C) <br /> The assembly shall automatically reduce the pressure in the <br /> "zone" between the check valves to at least 5 psi lower than Materials <br /> inlet pressure. Should the differential between the upstream and <br /> the zone of the unit drop to 2 psi, the differential relief valve shall Main valve body Lead Free*cast copper silicon alloy <br /> open and maintain the proper differential. Relief valve body Lead Free*cast copper silicon alloy <br /> Mainline valve body and caps including relief valve body and Elastomers Nitrile seat discs <br /> cover shall be Lead Free*cast copper silicon alloy. Check valve Diaphragms Nitrile, fabric reinforced <br /> moving member shall be center stem guided.All hydraulic <br /> sensing passages shall be internally located within the mainline Springs Stainless steel <br /> and relief valve bodies and relief valve cover. Diaphragm to <br /> seat area ratio shall be 10:1 minimum. Relief valve shall have a Model/Option <br /> removable seat ring. Check valve and relief valve components FS Flood detection sensor <br /> shall be constructed so they may be serviced without removing <br /> the valve body from the line.All seat discs shall be reversible. Approvals-Standards <br /> Shutoff valves and test cocks shall be full ported ball valves. pp <br /> The assembly shall be rated to 175 psi (12.1 bar)working • Approved by the Foundation for Cross-Connection Control and <br /> pressure and water temperature range from 32°F to 140°F(0°C Hydraulic Research at the University of Southern California <br /> - 600C).The Lead Free*Reduced Pressure Zone assemblies . AWWA C511 Conformance <br /> shall comply with state codes and standards, where applicable, <br /> requiring reduced lead content. <br /> The assembly shall meet the requirements of ASSE Standard A95E S A® U P� NSF <br /> 1013;AWWA Standard Code C511; CSA Standard B64.4; <br /> and approved by the Foundation for Cross-Connection Control 1013 B64.4 ed� <br /> NSF%N5161-G <br /> and Hydraulic Hydraulic Research at the University of Southern <br /> California. <br /> The assembly shall be FEBCO Series LF825Y, and shall include <br /> a sensor on the relief valve for flood detection. <br /> Dimensions -Weight <br /> Call customer service if you need assistance with technical details.
