Description
The circulation unit mod. M2025 - 34- 44 and M2025S - 34S - 44S is used to distribute the delivery fluid of the heating system at a temperature regulated by the motorized mixing valve with three-point actuator.
The installation is foreseen on the main manifold with a delivery / return center distance equal to 90mm.
It is composed by:
- Insulating shell made off closed-cell, cross-linked expanded polypropylene;
- Plant side : two-way shut-off valves 1 "F-F for connection to the system delivery/return, with integrated thermometers in the knobs;
- Non-return valve;
- Sector mixing valve with low leakage.
Available with different Kv values to offer the best precision characteristics and low pressure drops.;
- High efficiency circulator (also available model without circulator);
- Collector side: connections with flat flange and Ø 1 "F swivel nut.
