VFX, 2-, 3- and 3-way bypass fan coil valves
Valves, DN15-50, kvs 0.6-63, for control of heating and cooling in fan coil or chilled beams applications. The valves are intended to be used together with the thermal SE1 actuators. They are available as 2- and 3-way versions, as well as bypass versions. The valves have linear flow characteristics.
