User manual HONEYWELL V5012C

[. . . ] 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. [. . . ] The desired differential pressure can be preset from 0. 1. . . 0. 3 or from 0. 3. . . 0. 6 bar, depending on the type used.

The total pressure drop across supply and return valve, taking the V5012C Kombi-DP pre-setting into account, can be calculated with Honeywell's Valve Sizing Software at www. honeywell-valvesizing. com. The V5012C0103 is factory set to 0. 1 bar. The pre-setting can be increased to max. In that case the control curve as displayed in Fig. [. . . ] Lower pre-settings can be used to further throttle down the flow, see Table 4 on page 5.
