VFG315-2,7 VFG2...N/VFG3 - 2- and 3-way internally threaded control valves
Valves, DN15-50 kvs 0.63-39, 20 mm stroke, designed for control of hot, cold or glycol-mixed water in heating and ventilation systems. They also function very well in domestic water systems. The valves are intended for use together with SE5... actuators. Valves with DN32-50 may also be used with SE10..., if a larger actuating force is required.
