HeatBloC® K34 DN 25 (1")

Flat-sealing connections 1½" ext. thread incl.
1½" union nut for the installation on a PAW modular distribution manifold.With PAW mounting equipment the heating circuit can be installed on wall brackets.

Large ball valve handles
easy handling, visible closing position
3-way mixing valve with adjustable bypass
completely made of brass, linear characteristic (prevents temperature variation).Through the adjustable bypass on the front of the mixing valve 0 to 50 % of return water are mixed with the flow water, depending on the heating system.
