iverter and isolation valves for panel radiators 00, 0, 02, 0 series RIT LI 006/2 N ISO 900 M 2654 ISO 900 No. 000 unction aleffi 0 series valves are installed on panel style radiators. They are connected to the bottom supply and return ports, providing fluid flow to the upper thermostatic valve built into the radiator. The center-to-center dimension is 50 mm, which is the common standard for all brands of panel radiators. Two versions are available: iverter style for one-pipe systems; Isolation style for two-pipe systems. oth have two ball shut-off valves and come as either a through flow pattern for floor connections or angled flow pattern for wall connections. The diverter style offers an adjustable by-pass to send 0% to 50% of flow toward the radiator, factory-set for 5%. In addition, the diverter style contains a unique thermal break device in the return side (right leg) to prevent undesirable flow to the radiator due to thermo-syphoning when the thermostatic valve is closed, no call for heat.

They come in two versions: for two-pipe and one-pipe systems. oth are available (pipes exiting the floor) and angled (pipes exiting the wall). The two-pipe version is equipped with two ball shut-off valves; the one-pipe, in addition to the shut-off valves, is equipped with an adjustable by-pass from 0% to 50% of the flow rate towards the radiator, and a thermal break device () that prevents thermo-syphoning upward into radiator from by-passing flow. Since the radiators are in series in one-pipe systems, the downstream radiator receives water at a lower temperature than the upstream radiator. In most applications, it is recommended the number of radiators should be limited to to ensure sufficient heat delivery. Isolation valves and diverter valves are not necessary when directly connecting a panel radiator to manifold. Radiator adapter, code 94045, is used for direct pipe connection, PX, PX-L-PX, sweat or compression, to the radiator.
