Features of Automatic Softener Valve RUNXIN F77A/F77A3:
1) It adopts the seal slice, scuff resistance, corrosion proof for opening and closing. Mechanical part is more reliable.
2) Have keyboard locked function
3) LED colorful screen
4) If the power has been cut over 3 days, the clock figure will flicker continuously to remind to reset the current time, but other parameters are kept.
5) Brine refill is controlled by electric ball valve. Brine is refilled while service to save regeneration time.
6) It is suitable for filtration system.
7) Have output signal connector: There are three output signal connectors on PC board: N/O, N/C. COM which could be connected with booster pump and solenoid valve. When mode is b-01, the signal is sent at the moment while valve leaves from the position of running, and disappeared while it arrives at the running state. While mode is b-02, the signal is sent at the moment while valve leaves from each working position, and disappeared while it arrives at next state.
8) Have four modes of running counting:
A-01 is volume delayed. When it reaches at set volume and time, the valve starts to regenerate.
A-02 is volume timely. When it reaches at set volume, the valve starts to regeneration at once.
A-03 is intelligent volume delayed. By input resin volume, raw water hardness and regeneration modulus, the valve could calculated the capacity by itself. When it reaches at set volume and time, it starts to regenerate.
A-04 is intelligent volume timely. By input resin volume, raw water hardness and regeneration modulus, the valve could calculated the capacity by itself. When it reaches at set volume, it starts to regenerate at once.
9) Interlock function: The valve has function of interlock to realize only one valve in regeneration but the others are in running while several valves in parallel in system. In multi-steps treatment system such as in RO pre-treatment, when several valves are in series, there is only one valve is in regeneration or washing to ensure outlet water all the time while different valves in regeneration or washing. It could also realize parallel outlet water in several multi-steps pre-treatment, which means several valves are in series and parallel.
10) Remote handling connector: This valve has remote handling connector and could receive no power signal. In case of device check system water outlet is disqualified, the valve could receive signal to regenerate.
