US 7,460,013 B1 · Remotely actuated flood free zone valve

Abstract

A remotely-actuated residential water supply cut-off system is disclosed. A remotely-actuated cut-off valve interposed in a residential water line downstream of a pressure-reducing valve. An electronic actuator is mounted on the cut-off valve and is remotely actuated to drive a DC motor in a clockwise or counterclockwise direction to open or close the cut-off valve in response to a received signal. The electronic actuator includes a transceiver, a microcontroller and a motor. The microcontroller drives the motor to open or close the valve in response to a wireless signal received by the transceiver. A handheld transceiver unit sends a signal to the actuator to open or close the cut-off valve, or operate in automatic mode.

Dependent claims

A remotely-actuated residential water supply cut-off system for integration with a home security system comprising:

a remotely-actuated cut-off valve interposed in a residential water line downstream of a pressure-reducing valve;
an actuator including a transceiver and mounted on the cut-off valve and remotely actuated to open or close the cut-off valve in response to a wireless signal received by the actuator transceiver;
and
a wireless adapter unit, including a transceiver and microcontroller, integrated with the home security system and located remotely from the actuator for sending a signal to the actuator to close the cut-off valve when the home security system is armed, and a signal to return the cut-off valve to an initial position when the security system is disarmed.
