Flanged shut-off and balancing valve BRA.EKOFLUX S – DN 40, Kvs 55.6 m³/h
Code: EKOFLUX.S040Related products
Product detailed description
The EKOFLUX.S040 valve from the BRA.EKOFLUX S series performs three tasks in the pipework at once: it shuts off, allows measurement and balances the flow. In nominal size DN 40 with a Kvs of 55.6 m³/h, it is connected by flanges and installed in main circuits or individual branches of district heating and air-conditioning systems.
Why balance
If the flow is not distributed evenly between circuits or consumers, the system may become noisy, its components may be damaged and comfort decreases. Using the valve's continuous presetting, you set the required pressure drop and flow rate in each branch, so the system is balanced and energy consumption is optimised.
Setting and measurement
- scale showing full turns (basic setting) and tenths of a turn (fine setting), intermediate positions infinitely adjustable
- memory stop – after closing, the valve only opens up to the preset position; on DN 40 it is set with a 2.5 mm Allen key
- self-sealing brass pressure test points for connecting the probes of the measuring instrument
- pressure can be transmitted to the DPCV differential pressure controller
Materials
- body, cover and disc: ductile iron GGG40 (GJS400-15)
- operating stem and limiting screw: brass CW614N
- seal and O-rings: FKM
- handle: polyamide; bolts and nuts: stainless steel AISI 304
- finish: epoxy coating RAL 5002; flanges to EN 1092 / ISO 7005
Operating conditions
The medium can be water or a water-glycol mixture with no more than 50% glycol, at pressures up to 16 bar and temperatures from −10 to +120 °C. The valve can be installed in the flow or return pipe, but the flow must follow the arrow on the body. Every unit is tested to EN 12266 with leakage rate category A, and the valve complies with Directive 2014/68/EU. In DN 40 it weighs 9.7 kg.
Installation
Upstream of the valve, leave a straight run of at least 10× DN from a pump and 5× DN from an elbow or tee; downstream, at least 2× DN to an elbow or tee. The valve flanges must not be welded to the pipe, and the bolts are tightened gradually in a cross pattern. Installation should be carried out by a qualified person. The valve is not intended for gas, oils, hydrocarbons or aggressive, corrosive or abrasive liquids.
The BRA.EKOFLUX S series also includes sizes DN 50 (EKOFLUX.S050), DN 65 (EKOFLUX.S065), DN 80 (EKOFLUX.S080), DN 100 (EKOFLUX.S100) and DN 125 (EKOFLUX.S125).

Frequently asked questions
What is the EKOFLUX.S040 valve used for?
The valve shuts off, allows measurement and balances the flow in main circuits or branches of district heating and air-conditioning systems. Correct presetting eliminates uneven flow distribution, which causes noise and reduces comfort.
Can the valve be installed in the return pipe?
Yes, the valve is suitable for both flow and return pipes. You only need to observe the flow direction marked by an arrow on the body.
How does the valve keep its set position after closing?
The valve has a memory stop that limits opening to the preset value. On DN 40 the stop is set with a 2.5 mm Allen key, so after closing and reopening the valve returns exactly to the chosen position.
Which media can flow through the valve?
The valve is designed for water and water-glycol mixtures with up to 50% glycol. It is not suitable for gas, oils, hydrocarbons or aggressive or abrasive liquids.

IVAR designs, develops and manufactures highly energy-efficient heating and plumbing systems. We have over 10,000 catalogue items - mass-produced products and unique items - in addition to customised systems and combinations of complex products. And it’s all “Made in Italy”.
Vision
To make life easier for our clients, our clients' customers and our employees, thanks to our ability to be constantly innovative.
Mission
To design and manufacture advanced hydronic solutions that reduce installation complexity and energy consumption.
“Made in Italy” adds value
IVAR has been producing heating and plumbing system components since 1985: valves for heating bodies, direct heat metering modules, heat cost allocators, pipes and fittings, substations for heating systems, distribution manifolds, radiant panel systems, and components for solar and geothermal systems. And it’s all “Made in Italy”.
Over 200 people are employed at our manufacturing facilities in Prevalle (in northern Italy’s Brescia province). The site has been designed to streamline our many production and operational stages.
The Italian headquarters also acts as a hub for the wider IVAR Group, set up with the goal of distributing products beyond Italy’s borders. The group now has 11 branches, in Australia, Belgium, China, Germany, the United Kingdom, the Czech Republic, Romania, Slovakia, Spain, the United States and Tunisia.
Know How
Research, development and numerous laboratory tests guarantee that our clients’ requests can be translated into new high-efficiency products.
The stages required for production take place internally, beginning with hot forming, which is carried out at our subsidiary Valmon Stampati. Our continuous implementation of projects under the Industry 4.0 initiative also allows us to take full advantage of new releases in technology and IT to improve our manufacturing efficiency.
As a company, IVAR is constantly evolving. Every day, we invest in strengthening our products, in improving our production processes and in attaining new patents and certifications.
