VFTR - 2- and 3-way control valves
Valves, DN15-25, kvs 0.25-7.0, 5.5 mm stroke, intended for control of hot and cold water in climate, heating and ventilation systems. They can also control glycol-mixed water in for example liquid connected recovery systems. Intended to be used together with the SEZ4 actuators.
