CANARYPredictive Valve Integrity

Predictive Valve Integrity System

Your hydraulic valves already know they are failing. Nothing is listening.

CANARY installs inline between the plant and a hydraulic proportional or servo valve and runs a proprietary AI prognostic engine over the signals the valve has been emitting all along — current draw, spool behaviour, vibration, acoustic emission. In a 75-day pilot programme it forecast 17 of 17 predictable failures across seven degradation modes, with a minimum of 9.1 days’ warning, so the repair lands in a planned maintenance window instead of a stopped production line.

How we report performance. The headline figures above come from a 75-day pilot programme on a ten-valve fleet, not from simulation. Our Monte-Carlo simulation programme produced closely comparable results, which is the correlation we were testing for. Every number on this site states where it came from. See the full pilot results.

The problem

Fixed intervals get it wrong in both directions

Without condition data, a maintenance schedule is a guess. Guess short and you strip serviceable valves. Guess long and the valve fails between service windows and takes the line with it. Both errors are expensive, and most plants are making both at once on different assets.

Interval too short

Over-maintenance

Serviceable valves pulled, stripped and rebuilt on a calendar. Parts, labour and planned downtime spent on components that had useful life remaining.

Interval too long

Under-maintenance

Degradation outruns the schedule. The valve fails between windows, converting a planned repair into an emergency callout with the line stopped behind it.

The alternative

Service on condition

When the valve reports its own state continuously, the schedule stops being a guess. Work happens when the valve needs it, inside a window you chose.

What makes it different

Monitoring at the valve, not at the plant

It sits inline, and changes nothing

CANARY passes the supply and the full control signal straight through on a 12-pin input and a 12-pin output. It is a measurement device, not a controller: it never drives the valve, never intercepts a command, and leaves the existing control loop untouched. If the monitor loses power, the valve carries on.

It reads the signals that move first

Degradation begins as micro-changes in current draw, hysteresis, response timing and high-frequency acoustic energy — well below what a walk-round inspection or a handheld gauge can resolve. By the time a fault is visible to an operator, the valve is already failing.

A proprietary AI engine, not a threshold alarm

Anyone can tell you a valve has broken. CANARY runs a purpose-built prognostic model that fuses thirty engineering measurements, learns each valve’s own signature, and answers a harder question: how long until this reaches its limit. In the pilot it answered that question correctly seventeen times out of seventeen, and every time-to-failure estimate landed early rather than late. The output is a maintenance date, not a klaxon.

It tells you what it cannot see

A failure mode whose sensors are not fitted reports not monitored and names what it needs. It never shows a reassuring OK for something it is not actually watching. We think that is the minimum bar for a device people will plan around.

Coverage

Seven failure modes

Full detection detail

Spool & sleeve wear

Rising friction, a weakening centring spring, growing hysteresis and response threshold.

Silting

Fine particles settling in radial clearances while the spool rests, producing silt lock.

Erosion & internal leakage

Metering edges rounding, internal seals bypassing. Requires pressure transmitters on ports A and B.

Cavitation

Bubble collapse at the metering edges, detected by high-frequency vibration and acoustic emission.

Coil degradation

Shorted turns and insulation ageing, visible as rising current per unit command and estimated coil temperature.

Valve electronics

Ageing capacitors, a drifting power stage, position-sensor noise, connector and solder fatigue.

Wiring & supply

Corroding or loosening pins, a weak plant supply, voltage sag under load, surges.

And what it cannot

External weeping, a cut cable, a sudden spring break or a single large particle jam. No precursor, no prediction — we say so.

The prognostic engine

Proprietary AI, built for one job

CANARY does not run a generic anomaly detector. Its prognostic engine was developed specifically for hydraulic proportional and servo valves, trained against the physics of how those valves actually degrade, and proven in a 75-day pilot against seven distinct failure modes.

Multi-scale

Milliseconds and weeks, together

One branch reads high-frequency electrical transients; another reads degradation trend across 24-hour sequences. Fusing the two is what separates prognosis from detection.

Per-valve baseline

It learns your valve, not a spec sheet

Every judgement is made against that specific valve’s own commissioning signature. In the pilot, used and remanufactured valves were detected as reliably as new ones.

Thirty measurements

Corroboration before escalation

Thirty engineering measurements are tracked hourly. The engine requires agreement across several before it raises a WARNING, which is what holds the false-alarm rate down.

On-device

No cloud in the loop

Inference runs on the monitor itself. No plant network round trip, no subscription, and no dependency on a service staying available to form a judgement.

Universal by design

Built for a mixed valve fleet

Plants rarely standardise on one valve. CANARY is specified to fit across a fleet: connectors are built to match the valve at order, and the control signal is set in configuration rather than by buying a different model.

Connectors

Built to your valve

6+PE and 11+PE, DIN 43563, MIL-C-5015 7-pin and 12-pin, and the Form A, B and C solenoid connectors. Pin assignment matched from your data sheet.

Control signal

18 configurations

Not a ±10 V-only device. Six voltage ranges from ±2 V to ±10 V, and twelve current ranges from ±5 mA to ±100 mA including 4 to 20 mA.

Channels

Four universal inputs

Each configured independently, so the command and the actual-value feedback can run on different signal types on the same valve.
