ML8824-BV Series
Electric Actuator for PICVs
Honeywell ML8824-BV series PICV electric
actuators are designed for use with pressure
independent control valves (PICV) and provide a
wide range of features.
The ML8824-BV series actuator is available in
standard (ML8824A-BV) and NFC (ML8824B-BV)
versions. Models with the same close-off force
have the same technical specifications. An
Android APP is available for the NFC version,
which can be used to configure and view dead
band, sensitivity and maximum opening settings.
You can also configure the maximum flow rate and
view the current flow rate of the corresponding
PICV (VPIC Series DN25–DN150, readings are
based on laboratory test results).
Features
Self-adaption mode
Low power consumption
Quick and easy installation
Manual operation with override functions
DIP switch for configuring multiple parameters and functions
(e.g. run time, run direction, input signal and feedback signal,
etc.)
NFC function (NFC versions only) allows you to configure the
PICV's maximum flow rate and view the current flow rate via
mobile APP

A spring clip is used to connect to actuator to the valve rod, thus allowing the valve disk to move up and down for flow control.
- Page 4 Self-adaption mode Assemble the actuator and the valve and power the actuator with a 24 VAC/DC power supply. Automatic self-adaption: The actuator will automatically enter self- adaption mode when it is supplied with power. The yellow indicator light on the PCB will blink (1Hz) and the actuator will fully close (travel to the lowest position) and then fully open (travel to the highest position).
