RUNXIN F77BS
RUNXIN F77BS
The RUNXIN F77BS is a high-flow, manually operated multi-port valve designed for industrial and commercial water filtration systems. It is recognized for its simple, durable construction and utilizes a ceramic disc control system to manage the backwashing and rinsing cycles of filters, all without the need for electricity.

Primary Applications
Due to its high flow rate and durable manual design, the F77BS is used in situations where simple reliability and control are required:
- Industrial pre-filtration for larger facilities.
- Commercial de-ironing (iron removal) systems.
- Point-of-entry (POE) whole-home filtration for large residences or small communities.
- Mobile or temporary water treatment setups where electrical connections are not available.
Operational Modes
The valve follows a specific flow path to maintain the filter media (such as sand, activated carbon, or manganese sand):
- Service: Normal operation; water is being filtered.
- Backwash: Water flows upward through the filter media to lift, clean, and reclassify it. This position flushes accumulated dirt and debris to the drain.
- Fast Rinse: Water flows downward to settle the media bed and rinse away any remaining fine particles before returning to service.
Key Features
- Dual Valve Cores: It utilizes a unique internal structure where one core controls the inlet and the other controls the outlet, allowing for high flow efficiency and no water bypass during the rinsing cycle.
- Installation Versatility: The valve is natively a Top Mount design but can be converted to Side Mount using a specific side-mounted connector.
- Durability: The ceramic moving parts are resistant to wear and chemical corrosion, extending the valve's life significantly compared to traditional rubber-sealed valves.
- Manual Operation: It requires no electricity, making it ideal for remote locations or systems where automated control is not necessary.
