Product Features
Simple construction and reliable sealing
- Use of hermetically sealed ceramic sealing surfaces with high corrosion resistance for opening and closing
- Combined functions:
- For softeners: service, backwash, brine draw & slow rinse, brine refill, and fast rinse
- For filters: service, backwash, and fast rinse
No water flow during regeneration (single tank system)
- During regeneration, no water flows through the valve
Manual function
- Immediate regeneration at any time by pressing the “Manual/Return” button
Display after extended power interruption
- After a power outage longer than 3 days, the time display “12:12” flashes as a reminder to reset the clock
- All other parameters remain saved, and operation continues after power is restored
Automatic reset after power restoration
- After switching on the power, the valve automatically rotates for a few seconds to return to the position active before the power failure
Keypad lock
- If no operation is performed within 1 minute, the keypad lock activates (indicator light turns on)
- To unlock, press and hold the “Up” and “Down” buttons simultaneously for 5 seconds

Adjustable process parameters
- Depending on water quality and operating conditions, all process parameters can be adjusted accordingly
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 automatic multiport filter valves of the F67C series have a flow rate of 4 m³/h. They are equipped with a planar, corrosion-resistant sealing system for reliable opening and closing. The different operating functions – service, backwash, and fast rinse – can be configured through simple parameter adjustments. The F67C1 model is designed as a time-controlled version, while the F67C3 model operates as a volume-controlled (metered) version.
Product Features
Simple Construction and Reliable Sealing
Hermetically designed valve head surfaces made of high-quality ceramic with excellent corrosion resistance ensure reliable opening and closing. Supports the operating modes: service, backwash, and fast rinse.
No Water Flow During Backwash in Single-Tank Systems
During the backwash cycles, no water flows through the valve.
Manual Function
An immediate backwash can be triggered 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 configured parameters remain stored. After power is restored, the system resumes operation automatically.
LED Dynamic Display
Flashing bars on the display indicate that the valve is in service mode; otherwise, a backwash cycle is in progress.
Keypad Lock
If no operation is performed within 1 minute, the keypad lock is activated (indicator lights up). To unlock, press and hold the “Up” and “Down” buttons simultaneously for 5 seconds. This function prevents incorrect operation.
Adjustable Backwash Frequency
Multiple backwash cycles can be configured – for example, several backwash and fast rinse cycles within a single service cycle. This significantly improves the cleaning efficiency of the filter media.
Fully Adjustable Parameters
Settings can be flexibly adjusted according to water quality and operating conditions.
Selection Between Volume or Time Control
The valve is available either as a volume-controlled (metered) or time-controlled version.
External Control Input (Remote Handling Input)
This connection allows the valve to receive external signals, for example from PLC systems or computers, enabling remote valve control.
Interlock Function
When multiple valves are connected in parallel, the interlock function ensures that only one valve is in backwash mode at a time, while the others remain in service mode.
In multi-stage treatment systems (e.g. RO pretreatment) with valves connected in series, this function ensures continuous water flow even when different valves are backwashed sequentially.
The automatic multiport filter valves of the F67C series have a flow rate of 4 m³/h. They are equipped with a flat, corrosion-resistant sealing system for opening and closing. The different operating functions – service, backwash, and fast rinse – can be configured through simple parameter adjustments.
The F67C1 model is a timer-controlled version, while the F67C3 model is a volume-controlled (metered) version.

Manual Function
The backwash cycle 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 current time. All other configured parameters remain stored. Operation resumes automatically after power is restored.
Dynamic LED Display
If the bar on the display is flashing, the valve is in service mode; otherwise, a backwash cycle is in progress.
Keypad Lock
If no button is pressed within 1 minute, the keypad lock is activated (indicator light turns on). To unlock, press and hold the “Up” and “Down” buttons simultaneously for 5 seconds. This function prevents incorrect operation.
Backwash Frequency
Multiple backwash cycles can be configured, meaning several backwash and fast rinse cycles can be performed within a single service cycle. This improves the cleaning efficiency of the filter media.
Fully Adjustable Parameters
The parameters can be flexibly adjusted according to water quality and consumption.
Selection Between Metered or Timer-Controlled Version
The valve is available either as a volume-controlled (metered) or timer-controlled version.
Remote Control Input
The connection can receive external control signals and can be used together with PLC systems, computers, etc., for valve control.
Interlock Function
When several valves are connected in parallel, the interlock function ensures that only one valve performs backwash at a time while the others remain in service mode.
In multi-stage treatment systems (e.g. RO pretreatment) with valves connected in series, this function ensures continuous water flow while the valves perform backwash alternately.
