ESBE VTC 531

BOILER RETURN FLOW PROTECTION

3-way thermostatic valve ESBE VTC 512, 531

For installation in central heating systems, boiler + CAS

Three-way thermostatic valves ESBE VTC 512 and 531 are intended for

installation in central heating systems with solid fuel boilers (BioTec-L /

-C, BioTec Plus, EKO-CK P, EKO-CKB P, CentroPlus, - / B ...) and buffer

tanks CAS, all for the purpose of protecting boilers from condensation of

water vapor from flue gases. Valves ESBE VTC 512 and 531 enable quick

achievement and maintenance of the operating temperature of the

boiler by changing the ratio of the opening of the return flow from the

installation of central heating and short-circuit line from the boiler. A

circulation pump must also be installed in heating systems where ESBE

VTC 512 and 531 are installed.
