VFD3, 3-Way Control Valves with Internally Thread Union Connection, DN15–50
Valves, DN15-50, kvs 0.63-40, 20 mm stroke, intended for control of cold, hot and glycol-mixed water in heating, ventilation and domestic water systems. The valves are intended to be used together with Industrietechnik’s RVAN5 actuators. Valves with DN32-50 may also be used with RVAN10 if a larger actuating force is required.
