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, Settling, Acid-Alkaline Drawing, Acid-Alkaline Rinse, Drainage, Mixing, Rapid Drain and Fast Rinse.

• Manual function

  Realize regeneration immediately by pushing “Manual/Return” manual button at any time.

• Long outage indicator

  If outage overrides 3 days, the time of day indicator “‡”will flash to remind people to reset the present time. The other set parameters do not need to reset. The process will continue to work after power on.

• Buttons lock

  No operations to buttons within 1 minute, button lock indicator light on which represent buttons are locked. Before operation press and hold the “Up”and “Down” buttons for 5 seconds to unlock. This function can avoid incorrect operation.

• Signal output

  There is a signal output connector on main control board. It could control the booster pump on inlet of first and second grade demineralization system.

• Remote handling input

This connector can receive external signal, used together with PLC, computer, conductivity, resistivity etc. to control the valve.

• All parameters can be modified.

  According to the water quality and usage, the parameters in the process can be adjusted.

• Fast rinse first in case of stopping in service or power reconnected.

  Fast rinse first in case of stopping in service or power reconnected to avoid unqualified water entering into equipment.

• At the end of Backwash, interval open and shut-off water inlet to increase the effect of cation and anion resin layering.

  At the last minute of Backwash, interval 15 seconds to open and shut-off water inlet to increase the effect of cation and anion resin layering.

• Online monitory outlet water quality

  A resistivity meter is installed on the water outlet. In service position, if the resistivity of outlet water is unqualified for more than 20 seconds continuously, the system needs regeneration. In fast rinse position, if the resistivity of outlet water is qualified for more than 1 minute continuously, the system can turn to the service position.

• Multi-type programs for option

  Mixed bed system can select either single system operation or one valve in service one standby operation.

  The single system program has two types of operation programs: C-01 and C-02. It could be selected in program.

  When system set as C-01, use first grade demineralization to regenerate, while set C-02, use second grade demineralization to regenerate.

  Use a cable connecting two control valves for mixed bed. Program will automatically adjust to be one valve in service one standby. Use first grade or second grade demineralization to regenerate.
