RUNXIN F67Q Automatic Filter Valve 2.5″ Base
R2 505,00 Incl. VAT
The Runxin F67Q automatic filter valve automates backwash and rinse cycles on media filters with a 1″ inlet/outlet, 4 m³/h rating, programmable timing, and LED status display — ideal for residential and light commercial filtration.
Runxin F67Q Automatic Filter Valve
The Runxin F67Q is an automatic filter control valve designed to automate backwash and rinse cycles on media filter systems such as sand and activated carbon filters. It replaces manual valves with programmable automatic sequencing, improving cleaning consistency and reducing maintenance.
Equipped with a robust control head, the F67Q allows users to set backwash intervals using a timer measured in hours or days. An integrated LED dynamic display provides operational status, with flashing indicators during service and rinse cycles. The valve also retains settings after power interruptions and offers safety features like button locks and interlock functions for complex installations.
On systems where consistent water quality is critical — including residential filtration, swimming pool pre-treatment, and RO media polishing filters — the F67Q brings reliable automatic filtration control that reduces manual tasks while optimizing filter media performance.
📐 Filter Tank Sizing Guide
Selecting a compatible filter tank ensures efficient filtration and effective backwash cycles.
| Tank Diameter | Typical Use |
| 6″ | Small residential filters |
| 8″ | Standard home filtration systems |
| 10″ | Larger residential or light commercial applications |
| 12″ | High-capacity residential or small commercial filters |
Sizing Notes:
- Larger diameter tanks hold more media, improving filtration and reducing frequency of backwash cycles.
- Confirm that the chosen tank has a 2.5″-8 NPSM top mount compatible with the F67Q valve.
🕒 Backwash Timing Recommendations
Automatic backwash frequency depends on water quality and usage:
Time-Based Backwash
| Water Quality / Use | Suggested Interval |
| Light sediment | Every 2–3 days |
| Moderate sediment | Every 1–2 days |
| Heavy sediment | Daily or shorter cycles |
Notes:
- Time-only programming works well when water usage is consistent.
- If water usage fluctuates, shorter intervals ensure timely cleaning.
- Adjust based on observed filter performance and water clarity.
📌 Practical Installation Advice
- Mount on a top-mount filter tank with a 2.5″-8 NPSM fitting.
- Use correct pipe sizes (1″ inlet/outlet and drain).
- Program backwash intervals based on water quality and usage patterns.
- Test initial cycles and adjust timing as needed.
- Ensure a stable 12 V DC power source.
