RUNXIN F78B Automatic Filter Valve 40 m³/h

The RUNXIN F78B Automatic Filter is engineered for intensive industrial filtration workflows. It automates backwash and rinsing of media in high-capacity filter vessels, enabling up to 40 m³/h (≈40000 L/h) flow in suitable systems. Moreover, it features a hermetic distribution head, remote signal output, and volume‑based control mode, which significantly reduces manual labour and improves system reliability. hydrorigin.en.made-in-china.com+1

Key Features

• High Flow Capacity: Capable of treating up to ~40 m³/h, making it ideal for boiler feed, RO pre‑treatment, or municipal filtration applications.
• Automatic Control & Backwash: The unit handles service → backwash → rinse → service sequences automatically, saving operator time and ensuring consistent media cleaning.
• Hermetic Design & Reliability: Utilises hermetic head faces and a four‑piston distribution valve structure for a long, leak‑free service life.
• Remote Monitoring & Signal Output: Built‑in signal connectors enable remote monitoring and integration into SCADA or other control systems.
• Versatile Mounting & Compatibility: Side‑mounted installation with fitment on large tanks (24″–42″ diameter), suited for heavy‑duty installations.

Technical Specifications

• Inlet/Outlet Size: DN65 (~Ø75 mm UPVC connection)
• Operating Pressure: 0.2–0.6 MPa (≈2–6 bar)
• Temperature Range: 5 °C – 45 °C
• Suitable Tank Diameter: 24″–42″
• Control Modes: Volume‑based or time‑based automatic regeneration

Applications & Benefits

For large‑scale filtration systems, the RUNXIN F78B Automatic Filter offers both performance and convenience. For example, in RO plant pre‑treatment, it automates media cleaning, preventing fouled filters and downtime. Additionally, it supports boiler feed systems, municipal filters, or commercial water bottling lines where large flows and automated backwash are essential. As a result, operators gain reduced labour costs, improved uptime, and better water quality consistency.

Installation & Maintenance Tips

1. Ensure your filter vessel matches one of the supported diameters (24″–42″) and installation space allows side mounting.
2. Program regeneration settings according to your media type and usage volume; for example, every 24 hours or after a set volume of water.
3. Connect signal‑output wiring if monitoring or remote alerts are required.
4. Regularly inspect valve seating and head seals for wear, especially after high‑cycle usage.
5. Perform a full service back‑wash and rinse cycle at recommended intervals to restore media performance and prolong the system’s life.
