The combination of valve and actuator provides indicated flow rate back to the BMS via Modbus connection, allowing building operators to manage and refine the HVAC system to improve energy efficiency and reduce carbon emissions. 

Hattersley best in class PICV range delivers constant flow regardless of pressure fluctuations in the system. Combining this with the Modbus Actuators integrated library of Hattersley PICVs, the flow rate can be set remotely via the BMS, reducing commissioning time and simplifying control.
