Series A2C-WB Wall Box IntelliFlow Automatic Washing Machine Water Shutoff Valves with Leak Sensor are used in residential applications to protect against catastrophic water damage from a burst inlet hose connected to a washing machine in use or unattended. The Series A2C-WB IntelliFlow senses when the washing machine is on or off, and then opens or closes the hot and cold inlet valves as needed to allow or prevent water from flowing to the washer. If the Series A2C-WB detects a leak, current flow to both the hot and cold water valves are immediately interrupted and closed. It consists of an electrical three-prong outlet to receive a washing machine power cable, wall box, leak sensor, a power cord, and a replaceable internal strainer screen. Maximum Pressure: 150psi (10 bar).
