RUNXIN F77B1 Automatic Filter

The RUNXIN F77B1 Automatic Filter controls water filtration with ease. In addition, it handles up to 18 000 L/h, making it perfect for medium to large filtration systems. Moreover, the valve allows you to program backwash cycles using a clear LED display. As a result, it reduces manual work and ensures consistent filtration.

Furthermore, the F77B1 supports 2″ connections and offers flexible installation, either top-mounted or side-mounted. For example, its ceramic sealing faces prevent leaks and corrosion. Therefore, this automatic filter works well with sand filters, carbon filters, and pre-RO setups, making it ideal for industrial and commercial water treatment applications.

LED Dynamic Display & Button Lock: Displays current status and locks buttons to prevent accidental changes.
Flexible Mounting Options: Configurable for top‑mount or side‑mount installation.
Reliable Sealing & Construction: Uses ceramic sealing faces for corrosion resistance and leak‑free operation.

Application & Use Cases

This automatic filter valve is ideal for:

Sand or multimedia filters in industrial‑scale water treatment
Activated carbon filtration systems ahead of RO plants
High‑flow water refilling stations where automatic regeneration is required
Municipal or commercial filtration setups requiring reliable automated valve control

Installation & Maintenance Tips

Ensure the valve is mounted on a compatible vessel (24″‑30″ tank diameter) with correct inlet/outlet sizing.
Connect power (AC100‑240 V) and set up according to time‑clock or meter‑type controls as required.
Program backwash sequence (service → backwash → fast rinse → service) based on application and media type.
Monitor the LED display for service indicators or outage warnings. Buttons lock after 1 minute of inactivity to prevent tampering.
Clean or replace media as required and ensure the valve recalibrates correctly after servicing.
