“Demo-Bloc” Special tool Operating instructions Das Qualitätsmanagementsystem von Oventrop ist gemäß DIN-EN-ISO 9001 zertifiziert. Application: Failures of thermostatic radiator valves are frequently caused by impurity (welding beads, dirt particles etc.). This may affect the shut off function of the thermostatic radiator valve or may damage the seal of the valve disc. The Oventrop “Demo-Bloc” allows a quick and simple exchange of valve inserts for repair or cleaning without the necessity to drain the system. Moreover, Oventrop thermostatic radiator valves already installed may be upgraded with presettable valve inserts. The “Demo-Bloc” may be used for all Oventrop valves of the “Series A, AV 9, AV 6, ADV 6, AZ V, E, F, RF, RFV 6, KTB”, threeway conversion valves, “Hycocon ATZ, APZ, VTZ, VPZ, ETZ, HTZ” DN 15-25 (except for item no. 1068667) and “Cocon 2TZ” DN 15.
