1" 825Y-QT Quarter Turn Reduced Pressure Zone Assembly

Note: This item does not comply with the 2014 Lead Free Act. It may not be used in potable water applications as of January 4, 2014. For potable water applications 0683007 is recommended.

Series 825Y Reduced Pressure Zone assemblies feature a flood sensor with SentryPlus Alert technology to detect excessive water discharges from the relief valve. Activated through an add-on connection kit, the sensor can trigger the alert system sending notification of flood detection to facility personnel. Connection kits are available for BMS and cellular communication.

Features:

• Sensor on relief valve for flood detection
• Flood alerts feature available with add-on connection kit, compatible with BMS and cellular communication
• Provides mechanical protection of potable water against high hazard (toxic) cross-connection contamination
• Meets all specifications of AWWA, ASSE, CSA and approved by the Foundation for Cross-Connection Control and Hydraulic Research at the University of Southern California
• Modular relief valve for ease of maintenance
• Sizes 3/4 in. - 2 in. (20mm to 50mm)

Specifications:

The reduced pressure zone assembly shall consist of two independently operating, spring loaded, "Y" pattern check valves and one hydraulically dependent differential relief valve. The assembly shall automatically reduce the pressure in the "zone" between the check valves to at least 5psi lower than inlet pressure. Should the differential between the upstream and the zone of the unit drop to 2psi, the differential relief valve shall open and maintain the proper differential. Mainline valve body and caps including relief valve body and cover shall be bronze. Check valve moving member shall be center stem guided. All hydraulic sensing passages shall be internally located within the mainline and relief valve bodies and relief valve cover. Diaphragm to seat area ratio shall be 10:1 minimum. Relief valve shall have a removable seat ring. Check valve and relief valve components shall be constructed so they may be serviced without removing the valve body from the line. All seat discs shall be reversible. Shutoff valves and test cocks shall be full ported ball valves. The assembly shall be rated to 175psi (12.1 bar) working pressure and water temperature range from 32°F to 140°F (0ºC - 60ºC). The assembly shall meet the requirements of ASSE Standard 1013; AWWA Standard Code C511; CSA Standard B64.4; and approved by the Foundation for Cross-Connection Control and Hydraulic Hydraulic Research at the University of Southern California.
