Valve Signature™: see a valve changing while it still works
A smart actuator can tell you the valve is at 65%. Valve Signature™ is designed to tell you it reached 65% but needed more torque than at commissioning — and that its travel time is increasing.
Captures a baseline of current, travel, speed and position at commissioning and compares every subsequent movement against it.
Early sight of friction, binding, slowing or rising torque demand.

Valve Signature™ in practice
A baseline for every valve
At commissioning, the actuator records how that specific valve behaves: motor current through the stroke, travel time, speed and position. That becomes the valve’s own reference — not a generic threshold.
Every movement measured
Each subsequent operation is measured the same way and compared with the baseline. Rising load, slower travel or changes in the current profile show friction, binding or seat wear developing.
Before the position alarm
A conventional position alarm only triggers when the valve fails to reach its target. Valve Signature™ shows the trend long before that, while there is still time to plan an intervention.
No cloud required
The comparison runs in the actuator. Results are available locally and over BACnet MS/TP or Modbus RTU, and can optionally be aggregated in the RIFT Portal™.
