The new Butterfly Valve 565 is the best choice for optimizing piping systems built for water applications and a wide range of other applications. This new generation comes at a significantly lower initial cost, and will save even more thanks to its lower static weight, requiring less energy for both operation and transportation. Installing the Butterfly Valve 565 is quick and easy, but thanks to its extremely high durability, it will be almost maintenance-free during its long service life. 


Plastics do not corrode. The new Butterfly Valve 565 is made out of high-quality plastics that protect it from corrosion and abrasion. It therefore guarantees a longer lifetime and reduced maintenance and repair cost.

Direct Replacement

The Butterfly Valve 565 comes in the same installation length as metal solutions (DN50 – DN300). The exchange does not require any additional work on the pipes or new designs. This reduces the effort of both planning and installation, also thanks to a lighter weight.

60% lighter

Thanks to its low weight, a simple person can lift and install the Butterfly Valve 565 in just a few minutes. This also facilitates planning, since the low weight significantly reduces the need for costly transportation and personal.

High p/T performance

High-performance thermoplastics protect the Butterfly Valve 565 even under harsh conditions such as water hammers or extreme temperatures. The results are a reduction of both maintenance costs and production stops.

Sustainably future-proof

Lower production footprint

The waste of energy and resources in industrial production is reduced further by the long service life, thanks to a higher resistance against corrosion.

10 tons weight saved

Replacing 600 metal butterfly valves with the new plastic Butterfly Valve 565 will save up to 10 tons in weight and reduce CO2 emissions.

Lower overall costs

The low weight of the plastic material reduces the energy and resources needed for transport and installation. After installation, the advantages of the reduced static weight can become even more significant.
