From the valve to the whole fleet
RIFT is built in layers. Each one adds context to the last, and the actuator stays fully functional at every level — no cloud connection is ever required for basic control.
Layer 1
Actuator
What it doesControls the valve and measures every movement.
What you getPrecise control, open BMS data, local commissioning.
See the actuator range Layer 2
Valve Signature™
What it doesCaptures a baseline of current, travel, speed and position at commissioning and compares every subsequent movement against it.
What you getEarly sight of friction, binding, slowing or rising torque demand.
Explore Valve Signature™ Layer 3
Valve Condition Index™
What it doesTurns deviation, trend, usage and environment into a simple condition state.
What you getHealthy → Monitor → Service Recommended → Critical, readable by any BMS.

RIFT Sensor Hub™
What it doesAdds flow, differential pressure, temperature, leak and environmental sensing around the valve.
What you getUnderstand the cooling circuit or pipeline, not just the valve.

RIFT Portal™
What it doesSupervisory layer across every RIFT device on site or across sites.
What you getAsset health, trends, alarms and service planning for the whole fleet.
Explore RIFT Portal™ RAT understands the valve. Add the Sensor Hub to understand the circuit. Add the Portal to understand the estate.
Everything the BMS needs. Nothing proprietary.
BACnet MS/TP and Modbus RTU as standard. No proprietary gateway, no cloud dependency — the data model is documented for integrators and OEMs.

Frequently asked questions
Is RAT-DC suitable for PICVs?
RAT-DC is a quarter-turn platform for compact rotary valves. Most PICVs are linear-stroke and sit outside its first release.
What happens on power loss?
With the optional supercapacitor failsafe, stored energy drives the valve to its configured safe position under control, and stored-energy health is reported to the BMS.
How fast is RAT-DC?
10 seconds per 90° is the factory default, electronically configurable slower to suit the circuit.
Can we brand or integrate RAT into our product?
Yes — RIFT works with OEMs at design stage. See OEM & partner integration or contact the team.
