FANCOIL VALVES
Description:
The regulating valves for fan coil units of the 2131, 3131, and 4131 Series are used to control the flow of hot/cold water in heating and cooling systems and are operated by actuators with a 2.5 mm stroke, such as the electro thermal ones of the 22C, 22CX, 22CX5, and 26LC Series. The standard valve models are supplied in the following configuration with male thread: two-way (2131 Series); three-way (3131 Series); 3-way with 4 connections (4131 Series) and built-in bypass. Movement of the valve obturator is obtained by means of the electro thermal actuators of the 22C, 22CX, 22CX5, and 26LC
Series, available in the following models:
- NA (normally open) with 2 wires (standard) or 4 wires (with auxiliary micro switch contact);
- NC (normally closed) with 2 wires (standard) or 4 wires (with auxiliary micro switch contact).
All actuators can be easily attached to the valve body by means of a threaded bushing (M30x1.5).
