Mixing pump group
The mixing group DN 20 - ¾" "HV3-90" is a unit with 3-way mixing valve controlled by an electric rotary actuator and can be connected to any type of electronic heating controller.
The valve is supplied with 2 bypasses:
- upper by-pass (system side): it takes part of the water from the system return and flows it into the flow; therefore it allows to recover heat and balance the temperature; this is ideal for underfloor systems.
- lower by-pass (boiler side): allows the bypassing of the flow water in the presence of the circulator in the boiler and no hydraulic separator.

The unit is supplied with right flow.
