  • Gaskets: EPDM Pressure losses The pressure loss diagrams have been determined for the R387L straight valve and the R388L angled valve keeping one lockshield valve completely open and varying the number of turns to open the other. To determine the total pressure loss, the loss value for the supplying pipe and the one for the radiator with integrated thermostatic control must be added to the valve pressure loss.

Description

R387L straight and R388L angled twin-pipe valves have been designed for panel radiators with integrated control, with 3/4”E connection and 50 mm center distance. Panel radiators with 1/2”F connection can also be connected using a special adapter. R387L and R388L valves are equipped with internal lockshield valves on the two connections by which the flow can be intercepted isolating the panel radiators. The lockshield valves also enable to balance the circuits with an Allen key by varying the number of turns to open them (we recommend turning only one lockshield valve, leaving the other completely open).

If the panel radiators have 1/2”F connections, the R483Y002 special adapter with self-sealing gasket should be screwed on the panel radiator with a 10 mm hexagonal Allen key. After installing the adapter, connect the valve by tightening the nuts with a 30 mm hexagonal wrench. The valves are connected to the supplying pipes with Eurocono (R178E, R179E) or base 18 (R178, R179, R179AM) adapters, according to the version.
