BNT1650T Digital Flow-Controlled Valve
The BNT1650T Digital Flow-Controlled Valve is the brain of a water softening system; it manages regeneration by actual water consumption rather than by the calendar. Once the set volume is reached it automatically switches to a brine wash, saving salt and water, and its digital display keeps control simple.

01Problem & Solution
A Timer Valve Wastes Salt
Problem
Regeneration by the Calendar
Timer valves regenerate on set days whether or not any water has been used. That means salt and water consumed for nothing; when usage is low, the cost is simply wasted.
Solution
Washing by Actual Consumption
The BNT1650T Digital Flow-Controlled Valve meters the water that passes through it and switches to a brine wash only when the set volume is reached. The resin is used to its full capacity and both salt and water are saved.
02Key Features
Smart, Efficient, Durable
The BNT1650T Digital Flow-Controlled Valve is designed to get the most efficiency and the easiest operation out of a water softening system.
Flow-Controlled Regeneration
Switches automatically to a brine wash once the set water volume is reached, saving both salt and water.
Digital LCD Display
A user-friendly LCD showing the day, the regeneration mode and the remaining volume makes control straightforward.
Delayed Regeneration
Even when the set volume is reached, regeneration can be held back to a chosen hour so the wash runs when water use is low.
Totaliser Function
Tracks the total volume of water treated so you can follow how the system is performing.
Battery Backup
Holds the programme and clock for roughly 48 hours during a power cut so the settings are not lost.
Reliable Piston Design
The piston, seal and spacer design delivers durable, precise and long-lasting operation.

| Control | Flow-Controlled (Volumetric) | How the unit is managed. Automatic control needs no daily attention. |
| Inlet / Outlet | 1" | |
| Tank Connection | 2½" | Where it connects to the system. A building inlet and a flat’s internal plumbing call for different products. |

04Applications
Where Is It Used?
The BNT1650T Digital Flow-Controlled Valve suits systems of any size where efficient, automatic water softening is wanted.
- Domestic Softening
- Villas & Detached Houses
- Offices & Workplaces
- Cafés & Restaurants
- Commercial Softening
- Valve Replacement
- Tankless Systems
- Limescale Control
05How It Works
How Does the BNT1650T Digital Flow-Controlled Valve Work?
Softening (Service)
The valve passes water through the resin tank; the resin holds back calcium and magnesium, softening the water.
Flow Metering
The built-in meter continuously measures the volume passing through and tracks the softening capacity left.
Deciding to Regenerate
When the set volume is reached the valve decides it is time to regenerate; if the delay function is active it holds the wash until the chosen hour.
Brine Wash
The valve draws brine from the salt tank to renew the resin and sends the captured hardness minerals to drain.
Return to Service
Once the wash is complete the valve returns automatically to the softening position and the cycle begins again.
06Making the Right Choice
What Decides the Right Valve
When choosing the BNT1650T Digital Flow-Controlled Valve, flow requirement and tank compatibility need to be assessed correctly.
Flow Requirement
The system’s peak flow must suit the 4.5 m³/hour capacity; higher flows call for a larger valve.
Tank Compatibility
The valve’s 2½” tank connection and inlet/outlet diameter must match the existing resin tank.
Water Hardness
The hardness of the water determines the correct volume setting and how often regeneration occurs.
With or Without a Buffer Tank
Because it does not cut off raw water during the wash, it is particularly recommended for systems without a buffer tank.
07Maintenance and Use
Notes That Keep It Performing
- There must always be enough salt in the brine tank; when the salt runs out regeneration cannot take place and the water turns hard again.
- Volume and hardness settings must be made correctly from a water analysis; incorrect settings lead either to wasted salt or to hard water.
- Battery backup lasts roughly 48 hours; after a long power cut the time and date should be checked.
- The piston and seal assembly should be inspected periodically; the first installation is best carried out by a technical service engineer.
08Frequently Asked Questions
Common Questions
What does the BNT1650T Digital Flow-Controlled Valve do?
It is the digital control valve that manages a water softener’s regeneration. It meters the water passing through and, once the set volume is reached, automatically starts a brine wash to renew the resin.
How does it differ from a timer valve?
A timer valve regenerates on set days whether or not water has been used. A flow-controlled valve washes only when actual consumption reaches the set volume, which is what saves salt and water.
Is the water cut off during the wash?
This valve does not cut off raw water during the wash. That is why it is recommended for systems with no buffer tank; flow continues even during regeneration.
Does the valve treat the water itself?
No. The valve is not the component that treats the water but the control unit that manages the process. The resin softens the water; the valve runs the service and regeneration cycles automatically.
What connection and flow rate does it have?
The inlet/outlet connection is 1″, the tank connection 2½” and the flow rate roughly 4.5 m³/hour. It comes with a digital LCD display, delayed regeneration, a totaliser and about 48 hours of battery backup.

Installation and commissioning
Installation is a service · plumbing is the customer’s responsibilityThe system is delivered ready to install; it only needs to be connected to the inlet and outlet lines. If valve setup is required, we provide free support over a video call. Installation and commissioning fall under our service work and are subject to a service fee. Plumbing labour and any pipes, valves and fittings are not included in the price; these items are the customer’s responsibility.
Warranty
ConsumableThis product is classed as a consumable or spare part; because its life depends on use, it is not covered by warranty. Faulty or incorrectly shipped items are replaced — just get in touch with us.
