F111A3 RUNXIN WATER SOFTENER VALVE
The F111A3 Runxin Water Softener Valve is the flow-controlled automatic multi-port valve that forms the brain of an industrial water softener; by counting actual water consumption it regenerates the resin with brine at exactly the right moment, saving salt and water while keeping limescale treatment running without a break.

01Problem & Solution
Regeneration at the Wrong Moment
Problem
Salt and Water Down the Drain
Time-controlled valves wash to a calendar whether water has been used or not. At low consumption that wastes salt and water; at high consumption the resin becomes exhausted and hard water slips through to the plumbing.
Solution
Regeneration on Actual Consumption
The F111A3 Runxin Water Softener Valve meters the water passing through and starts regeneration when the resin is exhausted. Neither early nor late — it washes exactly when it needs to, and no salt or water is wasted.
02Key Features
Smart, Durable, Economical
The F111A3 Runxin Water Softener Valve is designed to bring efficiency and durability together in industrial softening systems.
Flow-Controlled Operation
Its metered design measures actual water consumption and starts regeneration exactly when it is needed.
Salt and Water Savings
With no unnecessary washes, salt and wash-water consumption fall markedly.
Ceramic Disc Sealing
A high-hardness ceramic disc design resists wear and corrosion for long service life.
Fully Automatic Cycles
It manages the service, backwash, brine draw, brine refill and fast rinse cycles itself.
High Flow Capacity
With a flow capacity of up to 20 m³ an hour it suits industrial-scale softening vessels.
Memory Retention
Settings are retained through a power cut, and the system picks up where it left off when power returns.
03Technical Specifications
Valve Specifications
| Feature | Value | What it does |
|---|---|---|
| Model | Runxin F111A3 | The manufacturer’s model code. Spares and service are matched by this code. |
| Valve Type | Automatic Multi-Port Softening | How the valve works. |
| Control Type | Flow / Meter | How the backwash timing is decided. A flow-controlled system saves both water and salt. |
| Flow Capacity | 20 m³/hour | How much water the unit can handle. Choosing above your need does not strain it; choosing below it does. |
| Sealing | Ceramic Disc | |
| Cycles | A Five-Stage Cycle | How the resin is regenerated. This is where salt consumption comes from. |
04Applications
Where Is It Used?
The F111A3 Runxin Water Softener Valve is used in industrial and commercial-scale limescale treatment systems.
- Industrial Softening
- Factories
- Hotels & Hospitals
- Boiler Feed Lines
- RO Pre-Treatment
- Residential Complexes & Apartment Blocks
- Laundries
- Valve Replacement
05How It Works
How Does the F111A3 Runxin Water Softener Valve Work?
Service (Softening)
Hard water enters the vessel through the valve, passes through the cationic resin and leaves as soft water with the hardness removed.
Flow Counting
The valve continuously counts the water passing through and calculates the exhaustion point from the hardness and resin values entered.
Backwash
When the resin is exhausted the valve moves to the backwash cycle; the bed is lifted and the accumulated contamination flushed to drain.
Brine Draw & Slow Rinse
The valve draws brine from the salt tank; the resin releases the calcium and magnesium it has captured and is renewed.
Brine Refill & Fast Rinse
The salt tank is refilled, the resin cleared by a fast rinse, and the valve returns to service.
06Making the Right Choice
What Decides the Right Valve
When choosing the F111A3 Runxin Water Softener Valve, flow rate, vessel compatibility and control type must be assessed correctly.
System Flow Rate
The facility’s peak flow must suit the valve’s capacity; excessive flow creates pressure loss.
Tank Compatibility
The valve’s vessel connection size and riser tube diameter must match the existing vessel exactly.
Control Type
Choose flow-controlled (A3) where consumption varies, and time-controlled where use is steady and predictable.
Resin and Hardness
Resin volume and inlet water hardness determine the regeneration parameters entered into the valve.
07Maintenance and Use
Notes That Extend Its Life
- The regeneration parameters — resin volume and hardness — must be entered correctly; wrong settings lead either to wasted salt or to hard water slipping through.
- The salt level in the brine tank should be watched; with no salt the valve still operates but no regeneration takes place.
- If there is sediment at the inlet a pre-filter should be used; particles wear the ceramic discs and the piston over time.
- The O-rings and sealing elements should be checked periodically, and installation is best carried out by a technical service engineer.
08Frequently Asked Questions
Common Questions
What does the F111A3 Runxin Water Softener Valve do?
It is the control centre of a water softener. By managing the service, backwash, brine draw, brine refill and fast rinse cycles automatically, it regenerates the resin with brine and keeps limescale treatment running continuously.
What does “flow-controlled” mean?
The valve regenerates on the volume of water that has passed through rather than on elapsed time. Because it meters consumption there are no unnecessary washes, which cuts salt and water consumption markedly.
How does it differ from the F111A1?
Both are softener valves in the same F111 series. The F111A1 is timer-controlled and washes at a set interval. The F111A3 is flow-controlled (metered) and washes on actual consumption, which is more economical where use varies.
Can it be used instead of a filter valve?
No. A softener valve has brine draw and brine refill cycles and is for resin systems. Sand and activated carbon units use no salt; there a filter valve such as the F111B series should be used.
What is its flow rate?
F111 series valves have a flow capacity of up to 20 m³ an hour. Actual flow varies with vessel size, resin volume, inlet pressure and the pressure loss in the system.
