541N SERIES Introduction The 541N Series are electronic 2- or 4-cycle regeneration control valves for softening of drinking and feed water supplies. When the drain solenoid is activated, the valve is automatically transferred to the regeneration position; together with the optional additional solenoid valve(s) integrated in the back cap of the control valve body, this simple and reliable system guarantees years of trouble-free service.
In case of the 541 valve, it also helps to keep the piston in the regeneration position when the operating pressure is extremely low (< 1,5 bar). Drain F.C. Tank inch Gal/min (l/min) (4,5) (4,5) (6,1) (7,6) (9,8) (13,2) Erie Water Treatment Controls – Belgium Page 5...
