RUNXIN F67P Automatic Filter Valve 2.5″ Base
R2 505,00 Incl. VAT
The Runxin F67P automatic filter valve provides programmable automatic backwash and rinse control for media filter tanks. It features 1″ connections, a top-mount design, LED display, and adjustable timing for efficient filtration maintenance.
Runxin F67P Automatic Filter Valve
The Runxin F67P automatic filter valve is a top-mount automatic control head designed to automate the backwash and rinse cycles on granular media filter systems — such as sand and activated carbon filters — commonly used in residential water filtration, swimming pool filtration, and RO pretreatment setups.
This valve replaces manual backwash valves or multiport controls, allowing the user to program cycle frequency based on hours or days using an integrated controller. An animated LED display provides clear status feedback, while programmable settings, memory retention after power outages, and safety lock functions help simplify ongoing maintenance.
By automating timed filter cleaning, the Runxin F67P helps maintain media performance, reduces manual intervention, and supports consistent water quality over time.
📐 Filter Tank Sizing Guide
Choosing the right filter tank size maximises filtration performance and reduces unnecessary backwash frequency.
| Tank Diameter | Typical Use |
| 6″ | Small residential filter (lower throughput) |
| 8″ | Standard domestic filtration systems |
| 10″ | Larger residential or pool pre-filtration |
| 12″+ | Larger domestic or light commercial systems |
Sizing Notes
- Larger tanks hold more media, reducing backwash frequency and improving head performance.
- Ensure the tank’s top mount is compatible with the 2.5″-8 NPSM valve base.
🕒 Backwash Timing Recommendations
The F67P uses a timer-based control to initiate cleaning cycles. Below are suggested initiating intervals — adjust based on water quality and usage.
Time-Based Backwash
| Usage/Water Quality | Suggested Interval |
| Light sediment load | Every 2–3 days |
| Moderate sediment | Every 1–2 days |
| Heavy sediment | Daily or shorter cycles |
Notes
- Shorter intervals may be necessary in high sediment or heavy use scenarios.
- Observe initial cycles and adjust timing to maintain clear effluent.
- Timer-based settings are ideal when water usage is relatively regular.
📌 Practical Installation Advice
- Mount to a compatible filter tank with a 2.5″-8 NPSM top mount.
- Use standard 1″ plumbing connections for inlet, outlet, and drain.
- Program initial backwash timing based on your water quality.
- Monitor early cycles to ensure effective rinsing and minimal media channeling.
- Ensure the supplied 12 V DC power adapter is correctly rated and installed.

FAQ's
1: What does the Runxin F67P automatic filter valve do?
It automates backwash and rinse cycles on media filter systems (sand, carbon) based on programmable timer settings, reducing manual maintenance.
2: What connections are used?
It uses 1″ female inlet, outlet, and drain connections — suitable for common residential filter setups.
3: Can the backwash frequency be adjusted?
Yes — the cycle timing can be set by hours or by days through the controller interface.
4: Does it retain settings after a power outage?
Yes — the valve retains programmed parameters, with only the time-of-day indicator requiring reset after long outages.
5: What size filter tanks is it compatible with?
The F67P works with standard top-mount filter vessels roughly 6″ to 14″ in diameter.
