Manifold DN 25 (LDP)

The LDP (low differential pressure) heating circuit manifold hydraulically decouples
the primary from the secondary circuit. If different volume flows result from
different generation and consumption structures, the water quantity required
to compensate for this is diverted via the overflow valve integrated in the manifold,
from the flow to the return chamber or vice versa. A faster shutdown of the
heating source is possible and pressure fluctuations in the system (due to sudden
closing of the secondary circuits) are reduced.
