Service
Backwash
Brine Draw & Slow Rinse
Brine Refill
Fast Rinse
For Filtration Systems:
Service
Backwash
Fast Rinse
No Water Flow During Regeneration
In single-tank systems, no water passes through the valve during the regeneration cycle.
Manual Operation
Immediate regeneration can be started at any time by pressing the Manual/Return button.
Display After Extended Power Failure
If the power supply is interrupted for more than 3 days, the display flashes 12:12 to remind the user to reset the clock.
All other settings are retained in memory, and the system resumes normal operation once power is restored.
Automatic Position Recovery
After power is restored, the valve automatically rotates for a few seconds and returns to the position it occupied before the power outage.
Keypad Lock
The keypad automatically locks after 1 minute of inactivity.
To unlock, press and hold the Up and Down buttons simultaneously for 5 seconds.
This feature prevents accidental changes to the programmed settings.
Time- or Meter-Controlled Regeneration
The valve can be configured for:
Time-based regeneration (after a preset number of days), or
Metered regeneration (based on water consumption).
Metered models are supplied with a flow meter and sensor cable, while time-controlled models are not.
Adjustable Operating Parameters
All operating parameters can be adjusted to match the water quality and specific application requirements, ensuring optimum system performance.
Product Features
Simple Construction and Reliable Sealing
The control valve uses hermetically sealed valve surfaces made of high-strength ceramic with excellent corrosion resistance for precise opening and closing. It combines the functions of service, backwash, brine & slow rinse, fast rinse, and brine refill.
No Water Flow During Regeneration (Single-Tank System)
In single-tank systems, no water flows through the valve during the regeneration process.
Manual Regeneration
Regeneration can be started manually at any time by pressing the “Manual/Return” button.
Display After Extended Power Failure
In the event of a power outage lasting more than 3 days, the time display “12:12” flashes to remind the user to reset the clock. All other set parameters remain stored. Once power is restored, the system automatically resumes operation.
Automatic Valve Reset After Power Restoration
After the power supply is switched on, the valve automatically rotates for more than ten seconds to return to the position it was in before the power failure.
Keypad Lock
If no operation is performed within 1 minute, the keypad lock is activated automatically, indicated by a control light.
To unlock, press and hold the “Up” and “Down” buttons simultaneously for 5 seconds. This function prevents incorrect operation.
Interval Backwash (Suitable for F68Q / F69Q)
For F68Q / F69Q upflow regeneration valves, interval backwash can be configured. This allows multiple operating cycles with only one backwash cycle.
The backwash interval setting depends on the local water turbidity: the lower the turbidity, the longer the backwash interval can be set.
Program Selection: Time Control or Volume Control
The valve can operate either in time-controlled mode (timer) or volume-controlled mode (meter).
When all symbols are illuminated, press and hold the “Manual/Return” and “Menu/Confirm” buttons simultaneously for 5 seconds to open the valve type selection menu.
The program mode should be set according to the product type.
Note:
Products with volume control are equipped with a flow meter and corresponding connection cable, while time-controlled models do not include a flow meter.

The F67C1 is a time-controlled model, while the F67C3 is a metered (volume-controlled) model that regenerates based on water consumption.
Product Features
Simple Design and Reliable Sealing
Hermetically sealed, high-strength ceramic sealing surfaces provide excellent corrosion resistance and ensure reliable valve opening and closing.
Supports the following operating cycles:
Service
Backwash
Fast Rinse
No Water Flow During Backwash
In single-tank systems, no water flows through the valve during the backwash cycle, ensuring efficient regeneration of the filter media.
Manual Operation
A backwash cycle can be started manually at any time by pressing the Manual/Return button.
Operation After Extended Power Failure
If the power supply is interrupted for more than 3 days, the display flashes 12:12, reminding the user to reset the clock.
All other programmed settings remain stored in memory.
Once power is restored, the valve automatically resumes normal operation.
Dynamic LED Display
A flashing indicator bar shows that the valve is operating in Service mode.
A steady (non-flashing) bar indicates that the valve is performing a Backwash cycle.
Keypad Lock
The keypad automatically locks after 1 minute of inactivity.
To unlock, press and hold the Up and Down buttons simultaneously for 5 seconds.
This feature prevents accidental changes to the programmed settings.
Multiple Backwash Cycles
Multiple backwash cycles can be configured within a single regeneration sequence.
This allows several Backwash and Fast Rinse stages to be performed, improving filter media cleaning efficiency.
Fully Adjustable Parameters
All operating parameters can be adjusted to suit the water quality and system operating conditions.
Choice of Metered or Time-Controlled Models
Available in both:
Metered (volume-controlled) versions
Time-controlled versions
Remote Control Input
The valve can receive external control signals and be integrated with PLC controllers, computers, and other automation systems.
Interlock Function
When multiple valves are connected in parallel, the Interlock function ensures that only one valve performs backwashing at a time while the others remain in Service mode.
In multi-stage water treatment systems, such as reverse osmosis (RO) pre-treatment systems with valves connected in series, the Interlock function enables continuous water supply by allowing the valves to backwash alternately.
