Oventrop extends its thermostatic valve programme
Oventrop extends its thermostatic valve programme by two series:
- “Series AV 9” for manual hydronic balancing
- “Series QV” for automatic hydronic balancing
Hydronic balancing is paramount for the efficient operation of a heating system. To achieve this, the volume flow is co-ordinated with each terminal unit.
The valves of the “Series AV 9” feature an infinitely adjustable valve insert for the exact adaptation of the volume flows which are determined by the calculated heat load. In this instance, the supply and return temperature as well as the existing differential pressure have to be taken into account. An exact positioning is ensured by the setting scale with
17 graduations. The valve insert, which is available separately, can be replaced by using the special tool “Demo-Bloc”.
The valves of the “Series QV” are thermostatic valves with an automatic flow controller and a setting scale. 17 succeeding presetting values allow adjusting the nominal value between 10 and 170 l/h. To carry out hydronic balancing, the determined maximum flow rate required for each terminal unit can be set directly at the valve and be maintained at a constant level. A complex calculation of the presetting value is no longer necessary. The integrated regulator ensures that the differential pressure within the “QV” valve remains constant and is not affected by pressure variations in the heating system. The valve insert, which is available separately, is especially suitable for the modernisation of existing heating systems as it fits all “standard” Oventrop thermostatic radiator valve bodies with connection thread M 30 x 1.5 (manufactured since 1999). The valve insert is replaceable without draining the system by using the special tool “Demo-Bloc”.
