Runxin F77AS Manual Softener – Durable & High‑Capacity Softening
The Runxin F77AS manual softener provides a robust and dependable solution for water-softening systems. Because regeneration is manual, you can control the cycle precisely. Moreover, this design helps you save salt and water during the brine refill process, and therefore increases system efficiency and longevity.
Key Features
- High Flow Rate: The valve supports up to 15 m³/h, which makes it ideal for large softening tanks.
- Inlet/Outlet Size: Uses 2″ male ports, which improves compatibility with big-diameter softener tanks.
- Drain Connection: Includes a 2″ male drain, allowing effective discharge during backwash.
- Brine Line Connector: Uses a ¾″ male connection for manual brine refill.
- Mounting Options: Can be mounted on top or side of the tank, giving installation flexibility.
- Base & Riser Pipe: Fits a 4″‑8UN base with a 1.5″ riser pipe for reliable installation.
- Operating Conditions:
- Pressure: 0.2–0.6 MPa
- Temperature: 5°C–45°C (some sources list up to 50°C)
- Turbidity: < 2 FTU for down-flow regeneration
- Sealing: Uses hermetic ceramic head faces, which resist corrosion and ensure a tight seal.
- Control Cycle: The handwheel lets you manually select these positions: Service → Backwash → Brine/Slow Rinse → Brine Refill → Fast Rinse.
- Brine Refill: Controlled by a manual ball valve, giving you full control over salt refill.
Benefits
- Precise Control: Since regeneration is manual, you control when and how often to regenerate, which helps save salt and water.
- High Capacity: With a 15 m³/h flow rate, the valve suits large softening setups such as boiler feed or commercial systems.
- Reliable Seals: The ceramic sealing maintains tightness and resists wear, so the valve lasts longer.
- Flexibility: Mounting options and manual control give you adaptability in system design.
- Efficient Brine Use: The manual refill valve allows you to manage salt use precisely.
- Robust Construction: Built for industrial-strength usage and long service life.
Ideal Applications
- Large residential or commercial water-softening systems
- Boiler softening systems
- RO pre-treatment systems using ion-exchange softeners
- Industrial softening setups with large resin tanks
