Product Description

Designed for installaton where TRVs are used, this Siemens BPV automatic bypass valve maintains a minimum flow rate in the heating system. When all TRVs are fully open the BPV will remain closed and full boiler output will circulate through the system, however, as the TRVs close the BPV will open for an optimum flow rate. Installing a BPV between the flow and return of a system minimises noise and vibration.
