Abstract: A valve assembly consists essentially of a valve body having an inlet port and an outlet port; a valve retainer at least partially housed within the valve body; a valve poppet positioned within the valve body; a magnet affixed within the valve body near the valve body inlet port; and a solenoid coil mounted around the valve body.

Abstract: A system for utility safety monitoring is disclosed. In an embodiment, the system includes a utility fluid meter coupled with a home or business structure, a local control unit, a home appliance with a failure sensor, a monitoring control center, and one or more shut-off valves. The failure sensor is coupled with an Internet of Things (IOT) platform such as a NodeMCU unit. The failure sensor detects a failure event of the home appliance and sends a notification to the local control unit. The local control unit then shuts down the one or more shut-off valves and sends notifications to a utility company and an owner of the home or business structure. The shut-off valve has a locking mechanism including a diaphragm, a locking component, a magnetic solenoid, and a locking shaft with a locking notch indicating a closed position.
