3-way mixing valve with 0-50% integrated by-pass
3-way mixing valve, with integrated by-pass, for pump units. Suitable for motorization and fully reversible (to be placed both on the left and on the right side of the pump unit). Connection to the circulating pump through the flanged side.
The built-in by-pass has an adjustable flow up to 50% of the total flow rate range of the valve (especially suitable for underfloor heating installations).
Made in Brass CW617N (CW614N). Yellow brass finish. The nut is not included.
It can be motorized by ModvlvS servomotors or by others on the market.
Working torque: less than 3 Nm.

PN 10. Max Temperature 110°C.
Kvs Value: 24,0. Maximum leakrate in % of flow: 0,05.
Dimension: 2" Male x 2" Nut (1”1/4 circulating pump).

The By-pass integrated into the 3-way mixing valve ensures a recycling inside the installation, even when the mixing valve is fully open. Through the by-pass, a fixed percent of the mixing (max. 50% of the total flow of the valve) can be set, in the case when the flow through the mixing valve is not sufficient.
Therefore, in case of a bad working of the system causing an increase of the temperature of the installation, the recycling through the by-pass allows a decrease in the temperature of the water in the underfloor installation. This can be done mixing the warm water of the return circuit with the hot water of the supply circuit, reducing possible damages.
