Modulo circuito di riscaldamento K32 DN 25 miscelatore a 3 vie senza pompa

The modular heating circuit K32 for heating systems controlled by a mixing valve. The connections of the heating circuit have an internal thread of 1". It also features large ball valve handles for easy handling and a visible closing position. The modular heating circuit is equipped with a design insulation with optimised function made of durable elastic EPP insulating the fittings 100%. Moreover, the system provides a ventilation opening to cool the pumps. Free access to the pump head is ensured by simply removing the front insulation shell. Additionally, the heating circuit provides a check valve (can be opened, 200-mm water column, spring-loaded) in the return pipe which prevents noise when electronically-controlled pumps are used, thus suited for horizontal and overhead installation. Standard installation of the flow is on the right, but flow and return line can be changed on site. All water-carrying parts are made of brass, the full-metal thermometer can be pulled off, with immersion sleeve integrated in the ball valve. The modular heating circuit is fully assembled with flat gaskets. The pump can be isolated, so no draining is necessary during service work.
