RUNXIN F77A Automatic Softener

Runxin F77A Automatic Softener — Efficient & Smart Water Softening

The Runxin F77A automatic softener offers precise, fully automatic water softening for homes, offices, and RO pre-treatment systems. It actively monitors water flow and regenerates the resin when needed, ensuring soft, clean water without manual intervention

Key Features

• Automatic Regeneration: The valve triggers regeneration based on either a timer or a flow meter, depending on your model. This keeps your system efficient and consistent.
• Durable Dual-Core Design: One core handles inflow and brine, while the other manages outflow and drainage, providing reliable performance.
• User-Friendly LED Display: The screen clearly shows whether the valve is in service or regenerating, making operation simple.
• Manual Regeneration Option: You can initiate regeneration anytime using the built-in button, which offers flexibility during maintenance or high water demand.
• Robust Construction: The ceramic head faces resist corrosion, extending the valve’s lifespan and reducing maintenance.
• High Flow Rate: The valve supports up to 18,000 L/h, which accommodates both residential and small commercial applications.
• Flexible Installation: You can mount it on top or on the side of the softener tank, depending on your setup.
• Ports & Connections:
• • Inlet/Outlet: 2″ (male)
  • Drain: 1.5″ (male)
  • Brine line: ¾″ (male)
  • Base Thread: 4″‑8UN, Riser Pipe: 1.5″ D‑GB
• Operating Conditions:
  • Water Pressure: 0.2 – 0.6 MPa
  • Water Temperature: 5 ‒ 50°C

Benefits

• Fully Automatic Softening: Regeneration is handled automatically, so you don’t need to trigger it manually or guess when to refill salt.
• Flexible Operation Modes: Choose between time-clock control or flow-meter control to suit your application and water usage.
• Low Maintenance: With durable ceramic sealing and strong components, the valve is built to last.
• User-Friendly: The LED display gives a clear status, and the manual regen button gives you control when needed.
