5600 SXT is a high performance control valve with multiple options for softener applications. Its backwash capabilities perfectly accommodate softener tanks up to 12" in diameter. Two non-corrosive, UV-resistant, fiber-reinforced noryl valve body designs are proposed: one for downflow regeneration and one for upflow (covers every valve in the 5600 family - quick access to all internal components). The valve is user-friendly, easily programmable and its modular design simplifies the disassembly and the maintenance.
