V5012C Kombi-Diaphragm Unit; Setting range 30...60 kPa (4.35...8.7 psi) differential pressure; for V5010 Kombi-3-plus BLUE DN10...DN40

Product Description

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-3-plus 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 preset level even under changing flow conditions. The V5012C Kombi-DP diaphragm unit can be fitted to the Kombi-Valves at any time, even when the system is under pressure and in operation - operation of the system does not have to be interrupted to install the V5012C Kombi-DP.
