Flow control | Residential controls | Siemens

When all TRVs are fully open the BPV will remain closed and the full boiler output will circulate through the system. As the TRVs close the BPV will start to open thus maintaining optimum flow rate through the boiler. Installing a BPV will minimise the noise and vibration often experienced when flow through the boiler diminishes.
