Connections

  • This 2.5 inch backflow preventer assembly features OSY (Outside Stem and Yoke) resilient seated gate valves. The main body includes groove end connections, and the OSY shutoff valves can be configured with either flanged or grooved inlet and outlet connections depending on the specific model. The primary image for this product depicts flanged connections.

SentryPlus Alert® Integration

  • The integrated SentryPlus Alert® flood sensor on the relief valve detects continuous or excessive water discharge. An add-on sensor connection kit allows for extended flood monitoring, enabling integration with Building Automation Systems (BAS) via RS-485 Modbus or the Nexa® platform through Wi-Fi connectivity for remote alerts.
