Caleffi 549567A Hydraulic Separator 1-1/4" Press Union 150 PSI

The Caleffi 549567A Hydraulic Separator 1-1/4" Press Union 150 PSI is a hydronic component used to separate primary and secondary water circuits while allowing controlled flow balance between them. It reduce interaction between circulating pumps by decoupling pressure differences, stabilising flow distribution across heating and cooling loops. In HVAC systems it is installed in hydronic piping networks where multiple circuits operate under different load conditions. It supports proper system hydraulics flow interference, improving temperature control consistency and ensuring more stable operation of boilers, chillers and associated distribution piping under conditions.
