F74B Automatic Multiport Softener Valve
The F74B automatic multiport softener valve features a flow rate of 10m3/h and adopts a planar and corrosion resistant gasket for opening and closing. Backwash, brine and slow rinse, brine refill, and fast rinse functions can be realized by this valve.
Simple structure and reliable sealing
It adopts hermetic head faces with high degree pottery and corrosion resistance for opening and closing. It combines with Service, Backwash, Brine & Slow Rinse, Brine Refill and Fast Rinse.
Variety of installation methods
Use side-mounted connector can change N74B from top mounted to side mounted, and screen is movable.
No water passes the valve in regeneration in single tank type
Manual function
Realize regeneration immediately by pressing“Manual/Return”at any time.
Long outage indicator
If outage overrides 3 days, the time of day indicator “12:12” will flash to remind people to reset new time of day. The other parameters do not need to reset. The process will continue to work after power on.
LED dynamic screen display
The stripe on dynamic screen flash, which indicates the control valve is in service, otherwise, it is in regeneration cycle.
Buttons lock
No operations to buttons within 1 minute, button lock indicator lights on which represents buttons are locked. Before operation, press and hold the “Up” and “Down” buttons for 5 seconds to unlock. This function can avoid incorrect operation.
It can choose time clock type or meter type by program selection.
Can realize interchange between time clock type by day or by hour and meter type by dialing a switch on main control board. (Check figure on P18) (Attention: After dialing the switch, it needs to reconnect the power. The meter type product has one flow meter and flow meter cable, but the time clock type product doesn’t have.)
Four kinds of meter type can be selected (Suit for F74A3, F74B3)
Mode | Name | Instruction |
A-01 | Meter delayed regeneration | Regenerate on the day although the available volume of treated water drops to zero (0). Regeneration starts at the regeneration time. |
A-02 | Meter immediate regeneration | Regenerate immediately when the available volume of treated water drops to zero (0). |
A-03 | Intelligent meter Delayed regeneration | Meter delayed regeneration type, but by setting resin volume, feed water hardness, regeneration factor, the controller will calculate the system capacity. |
A-04 | Intelligent meter immediate regeneration | Meter immediate regeneration type, but by setting resin volume, feed water hardness, regeneration factor, the controller will calculate the system capacity. |
Interlock Function
It has a function of interlock to realize only one valve in regeneration but the other valves are in service while several valves parallel in system. In multi-steps treatment systems such as RO pre-treatment, when several valves are in series, there is only one valve in regeneration or washing to ensure pass water all the times while different valves in regeneration or washing.
