Fleck 5800 SXT Control Valve
The Fleck 5800 SXT control valves are Fleck’s most modern yet easy to service valves, as the valve has very few moving parts as well as using snap-together plates and a single programming board. An LCD backlit display helps to program in low light conditions. The control setup of capacity, regeneration time and days override is quick and easy. The SXT controller also allows for additional programming of up to 20 different cycle steps. Learn more about the 5800 series here.
