Caleffi's 519 Series prevents excessively high head pressure (a result of the branch piping 2-way zone valves closing)by allowing flow from the supply piping directly to the return piping. A DPBV can be installed at the end of a zone valve piping circuit, or at the beginning, after the pump discharge. * Equals the promotional purchase amount divided by 6 (excluding taxes and shipping charges) rounded to the next highest whole dollar. The 519 Series will open to start bypassing flow when differential pressure reaches the adjustment setting. endstream
