Mixed heating circuit station Regumat M3-220
DN 40, Wilo Stratos Maxo 40/0.5-8

For the connection of a mixed heating circuit. The stations include all components which are necessary for the connection of heat generators, pumps and pipework. The stations enable the heating circuit to be shut off on the supply and return sides. The check valve in the return pipe prevents incorrect circulation. Flow and return can be changed individually on site.

The stations consist of a shutoff device with two ball valves to shut off the heating circuit, two thermometers integrated in the handles to display the flow and return temperatures, a check valve to prevent incorrect circulation, a three-way mixing valve with actuator and a thermal insulation. Depending on the model, a pump ball valve is also included for easy pump replacement without draining system parts.

The Regumat stations are characterised by a time- and space-saving installation of the boilers to the pipework systems. A high degree of functional reliability is ensured by maintenance-free components and high-quality materials. The stations can be modularly extended with various accessories.
