F111B1 Runxin Filter Valve
The F111B1 Runxin Filter Valve is the time-controlled multi-port filter valve that takes charge of automatic sand and activated carbon units; by backwashing the unit at set intervals it flushes out the contamination collected in the filter bed and keeps the system efficient with no human intervention.

01Problem & Solution
A Blocked Filter Bed
Problem
Contamination Builds Up in the Bed
The sediment, silt and contamination captured in sand and activated carbon units build up in the bed over time. An unwashed filter blocks, pressure falls and treatment efficiency drops markedly.
Solution
Automatic Backwash Control
The F111B1 Runxin Filter Valve backwashes the unit automatically at the set interval. The contamination collected in the bed goes to drain, the filter is refreshed and the system carries on working efficiently.
02Key Features
Automatic, Solid, Practical
The F111B1 Runxin Filter Valve is designed to look after filter units with no human intervention.
Time-Controlled Washing
It backwashes the unit automatically at the set interval in days or hours, with no manual intervention.
Suits Sand and Carbon
A filter valve designed to control automatic sand units and activated carbon units.
Chemical-Free Cleaning
No chemicals or salt are needed for backwashing; the system cleans itself with water alone.
Corrosion-Resistant Construction
Corrosion-resistant seals and body give long service life in demanding conditions.
High Flow Capacity
With a flow capacity of up to 20 m³ an hour it suits industrial-scale filter vessels.
Extends System Life
Regular backwashing keeps the filter bed from blocking, preserving the unit’s efficiency and life.

| Model | Runxin F111B1 | The manufacturer’s model code. Spares and service are matched by this code. |
| Valve Type | Automatic Multi-Port Filter | How the valve works. |
| Control Type | Time (Timer) | 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. |
| Cycles | Service · Backwash · Rinse | How the resin is regenerated. This is where salt consumption comes from. |

04Applications
Where Is It Used?
The F111B1 Runxin Filter Valve is used to automate backwashing filter units.
- Automatic Sand Units
- Activated Carbon Systems
- Well Water Systems
- Factories
- Hotels & Housing Estates
- RO Pre-Treatment
- Central Water Lines
- Valve Replacement
05How It Works
How Does the F111B1 Runxin Filter Valve Work?
-
Service (Filtration)
Raw water enters the vessel through the valve, passes through the sand or activated carbon bed and leaves treated at the outlet.
-
Time Tracking
The valve counts the interval in days or hours entered into it and waits for wash time to arrive.
-
Backwash
The valve reverses the flow; the bed is lifted and the accumulated sediment and silt flushed out through the drain line.
-
Fast Rinse
After the wash the bed is settled and rinsed, returning it to the right condition for filtration.
-
Return to Service
When the cycle is complete the valve returns to service and filtration continues without interruption.
06Making the Right Choice
What Decides the Right Valve
When choosing the F111B1 Runxin Filter Valve, unit type, flow rate and vessel compatibility must be assessed correctly.
Unit Type
Backwashing filters such as sand or carbon need a filter valve; resin systems need a softener valve.
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.
Contamination Load
The sediment load of the water determines how short the wash interval needs to be.
07Maintenance and Use
Notes That Extend Its Life
- The backwash period should be set from the contamination load of the water, with a shorter interval where contamination is heavy.
- Confirm that the drain line is clear and of adequate capacity; a blocked drain prevents washing.
- The pressure differential between inlet and outlet should be monitored; a marked drop can point to blockage in the bed.
- 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 F111B1 Runxin Filter Valve do?
It takes charge of automatic sand and activated carbon units. By backwashing the unit automatically at set intervals it flushes the contamination collected in the bed to drain and preserves the filter’s efficiency.
Does it soften the water?
No. This is a filter valve with no brine draw or brine refill cycle. It cleans a sand or carbon bed but does not remove hardness (limescale). Limescale treatment calls for a resin system with a softener valve.
How does it differ from a softener valve?
A filter valve’s cycle is service, backwash and fast rinse. A softener valve additionally has brine draw and brine refill cycles, because the resin has to be regenerated with salt.
What does “time-controlled” mean?
The valve starts the backwash automatically at the interval entered, in days or hours. It is a practical, economical method of control for filter applications where use is regular and predictable.
Are chemicals needed for backwashing?
No. A backwash run by a filter valve uses no salt and no chemicals; the system cleans itself with water alone. That keeps running costs low.
