[. . . ] V5012C Kombi-DP Diaphragm Unit RETROFIT AUTOMATIC DP CONTROLLER PRODUCT DATA Application The V5012C Kombi-DP diaphragm unit is installed onto a V5010 Kombi-3-plus BLUE or V5032 Kombi-2-plus return mains balancing valve and connected to a V5000 Kombi-3plus RED or V5100 Stop Valve-3 supply mains valve with the supplied impulse tube. It is used in systems with variable volume flows, for example two-pipe heating systems or district heating exchangers, and supports a hydronic balance by keeping the differential pressure over consumers at a constant pre-set level even under changing flow conditions. [. . . ] When the supply pressure decreases, the diaphragm inside the Kombi-DP is pushed open by the return pressure. The diaphragm moves up, releasing the insert of the return valve and the flow increases. The desired differential pressure can be preset from 0. 1. . . 0. 3 or from 0. 3. . . 0. 6 bar, depending on the type used.
