Honeywell ML8824M series multifunctional linear electric actuators are used to control linear electric valves – Pressure Independence Control Valves (abbreviation: PICV) and electric globe valves. ML8824 series electric linear actuators can be connected to dedicated temperature sensors and pressure sensors and transmitted to the controller through the Modbus protocol for parameter collection of various control applications (supply and return water temperature difference control, pressure difference control, return water temperature control, etc.).

ML8824 series electric linear actuators are equipped with Honeywell PICV (VPIC series) and dedicated temperature sensors can achieve energy consumption calculating for qualitative analysis of energy consumption of air-conditioning equipment. ML8824 series electric linear actuators use Modbus RTU communication protocol, which can quickly and accurately transmit data to ensure more accurate valve control. Various parameters can be set and modified through register addresses to achieve different control requirements.
