Butterfly Valve 565


The plastic Butterfly Valve 565 is the ideal solution for reliable fluid control for all water- and water treatment applications. The interoperable and lightweight plastic valve is available in both wafer- and lug-style, covering many applications.

Quality assurance at GF Piping Systems

With our accredited in-house testing laboratory, we can test the Butterfly Valve 565 according to industry standards. Amongst other tests, we can do endurance testing according to ISO 16136, the relevant product standard for industrial butterfly valves. This way, we can ensure our products meet the market requirements and exceed pressure ratings.

Properties & applications

Built for the future

At GF Corys, we understand that different challenges require adjustable solutions. This is why we revolutionized the well-proven design of lug-style butterfly valves. Adding plug-in lug inserts ensures the highest compatibility, flexibility, and increased sustainability.

The addition of the Butterfly Valve 565 Lug-Style completes our high-quality plastic butterfly valve range, offering versatile solutions for water and water treatment applications, featuring a unique body design allowing it to serve as an end valve, streamlining one-sided disassembly for maintenance of filters, tanks, and installations.

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.
