The document describes a smart water valve that is designed to prevent water damage from issues like leaks or continuously running toilets. It works by learning the normal fill time for an appliance, like a toilet, and shutting off the water if it detects flow for longer than expected. The valve uses magnetic sensing of water flow and patented latching technology to operate reliably. It is aimed at helping to reduce unintended water loss and damage in homes and businesses.

2. Introduction – Goals / Objectives
 Castlebridge Enterprises, Inc. is an environmental
care, technology development partnership with a goal
of developing innovative solutions and products that
conserve water, and mitigate water damages by
reducing unintended water loss.
 Innovation and development was sparked by the
partners’ own personal experiences in which
unintended water loss and property damage
occurred. This, they learned, was a commonly shared
problem.
 When searching for a solution, they could not find a
simple and practical product available on the market.

4. Market Background
 Many water conservation efforts are directed at reducing
the use of water by limiting volume or flow of water.
Examples of this are low volume flush toilets and low flow
shower heads.
 Little has been done to limit water consumption and
damages in situations where something has gone terribly
wrong. Examples of these are; toilets that continue to run
and broken or ruptured connection hoses.
 Insurance industry studies find these failures are the
major reason for insurance damage claims.
 In many situations the water may just continue to run for
days, unnoticed and undetected. Even the smallest leaks
can add up to thousands of gallons a month.

5. Real Problems – Smart Water
Valve is the Answer
 Burst Supply Lines or leaking fittings.
 Water spills and overflows onto the floor
 Toilets with Flushing Valves that hang-up and
water continues to run down into the bowl
undetected for hours.
 Toilets that have developed a leak past the
Flushing Valve and a cyclic slow drain down
and refill of the Tank occurs
 Toilets will faulty Refill Valves and the water
continues to run and goes down the overflow
tube into the bowl undetected for hours.

8. Principle of Operation
 The Smart Water Valve determines the fill time, or
normal use cycle, required to operate the water
appliance.
For example: When the toilet is flushed, it will time
the refill event and add a convenience factor of 150%
to the fill time. This calculated set time is to
accommodate occasional back to back flush
sequences and avoid inconvenience for the user.
 In normal operational use, with the onset of water
flow, the Smart Water Valve compares the actual
elapse time to the set time it has stored for the water
appliance.
 If the water flow continues, (even those flows in the
drips /sec range) and the elapsed time exceeds the
set time the Smart Water Valve will close, stopping
the water flow to the appliance.

14. Technology Differentiators
Normal Operating State
• Water flows through the valve
body past the valve plug and seat.
• Water flow moves the flow
detection ram into coil magnetic
field, altering coil inductance.
• Microprocessor detects inductance
change, starts timer and checks
against initial set-up time
Closed State
• Microprocessor determines that
the flow exceeded initial set-up
time.
• Microprocessor sends signal to
energize actuate coil, releasing
Actuate Lever
• Actuate Lever moves to visible trip
position, and plug moves to close
off water flow.

Circuit
◦ Detecting water flow at the start and end
of a water use cycle is critical. Sensing
flows as small as 10 drips/sec. is
accomplished by using a ferrous Flow
Ram that is moved by the flow of water.
As the Flow Ram moves, the measured
coil inductance increases.
◦ The result is a very repeatable and dependable flow detection
method without hysteretic effects seen in discrete switch flow
rams.
◦ The Flow Ram is the only wetted moving part.

16. Technology Differentiators
Actuate Lever Mechanism
◦ The Actuate Lever is held in the “Latched
Position” by a permanent magnet, core,
and pole piece. No battery power is
consumed to securely maintain the
Actuate Lever in the "Latched" state.
◦ The Actuate Lever is toggled to the “Un-
latched position” when the
Microprocessor signals to electrically
energize the coil, This counters the
permanent magnet in the circuit and
releases the Actuate Lever to toggle to
the “un-latched” position, allowing the
plug stem to travel to the closed position.

18. Technology Differentiators
 Firmware Functionality
◦ Set Mode (learn and set the duration time for normal water event)
Press Set-Up/Test button for 3 sec. User then starts the normal use flow event, for
example, flush the toilet. After holding test/set button for 3 sec, 1 audible beep is
heard followed by green LED flash every sec until flow is detected then red LED flashes
until flow event has ended. Water valve automatically set flow duration time and exits
Set Mode.
◦ Test Mode (close valve)
Press and release Set-Up/Test button for < 3 sec. Audible beep is heard and the valve
automatically trips and closes. Valve can be reset (open) by manually rotating up the
Actuate Lever.
◦ Flow Detect-(normal operation)
Green LED Flashes 1 time every 4 seconds while flow is ongoing.
◦ Flow Detect-(abnormal, flow exceeds preset time)
Green LED Flashes 3 times, simultaneously with 3 audible beeps, actuate function
closes valve.
◦ External Leak Detect 1-(leak detected but no flow is detected)
Red LED Flashes 1 time every 4 seconds for as long as leak is detected for up to 10
min. No other action taken.
◦ Eternal Leak Detect 2 -(leak detected for more than 10 min or if flow is also detected)
Audible beep 3 times and Red LED flashes 3 times,. Indicates that leak has been
detected and valve will actuate.
◦ Cyclic Leak Detect-(Water used on a periodic basis, like a leaking flushing valve)
Audible Beep 3 times each beep followed by Red and Green LED Flashes. Followed by
actuate function which closes valve.
◦ Change Batteries
Audible Beep 1 time and Red LED flash 1 time
