How does a picv work
WebThe use of a PICV, as with all 2 port control valves, allows for the variation of the flow rate to vary the heat output of the terminal unit. The PICV is an integral part of the control loop. 4. Thermostat, BMS, PICV & Terminal Unit By varying the flow rate we can control the heat output of the terminal. For PICVs with an WebThe PICV is a control valve with close tolerance flow paths. Flushing through these valves may introduce debris which could block the flow paths.
