N74A1 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 pressingManual/Returnat 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 doesnt 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.
