Up for sale is a premium, commercial-grade Oventrop Combi 2 radiator service valve. Often utilized in high-end residential or commercial hydronic heating layouts (including pairing with premium systems like Runtal radiators), this valve connects to the lower supply/return pipework to allow individual room balancing, proportional presetting, and complete isolation of the radiator when maintenance or drainage is required.
