Product description

N74A Automatic Multiport Softener Valves

Featuring a flow rate of 10m³/h, the N74A automatic multiport softener valve can realize different functions such as service, backwash, brine and slow rinse, brine refill and fast rinse through various parameter modifications.


Product Characteristics

  • 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 N74A3, N74B3)

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.
