ValVes for single-pipe and twin-pipe systems Single-pipe and twin-pipe val veS for panel radia torS r383 and r384

Description

R383 straight and R384 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. R383 and R384 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). A third lockshield valve positioned on the by-pass allows to obtain the two possible versions (single pipe or twin pipe) depending on the type of system on which the valves are installed Versions and product codes Series Product code Connections “Panel radiator x Pipe” Version R383 R383X001 3/4”F x base 18 straight R383X011 1/2”M x base 18 R383X002 3/4”F x 3/4”E R383X012 1/2”M x 3/4”E R384 R384X001 3/4”F x base 18 angled R384X011 1/2”M x base 18 R384X002 3/4”F x 3/4”E R384X012 1/2”M x 3/4”E Notes.

  • Temperature range: 5÷110 °C
  • Max. working pressure: 10 bar
  • Connections center distance: 50 mm
  • Non-preferential delivery and return connections
  • System connections with 3/4”E adapter or base 18
  • Balancing lockshield valves adjustable with 6 mm hexagonal Allen key
  • By-pass lockshield valve adjustable with 6 mm hexagonal Allen key Pressure losses The pressure loss diagrams have been determined for the R383 straight valve and the R384 angled valve in twin pipe version (by-pass lockshield valve closed) keeping one lockshield valve completely open and varying the number of turns to open the other. In single pipe version the two lockshield valves are fully open and to vary the opening of the by-pass lockshield valve are obtained variations of water flow to the panel radiator.

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. After installation proceeds with the balancing of the valve acting appropriately on lockshield valves according to requirements by following the calibration diagrams.
