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.
Built for the future
With the Butterfly Valve 565, GF offers high-quality thermoplastic butterfly valves for all water and water treatment applications. Launched in 2021, the 565’s success began with the introduction of the Wafer-Style valve. In 2024, GF unveiled the 565 Lug-Style, expanding its versatility further. One year later, the 565 Big completes the portfolio by providing dimensions from DN350 to DN600*.
The thermoplastic solution smoothens the path to a more sustainable future by being up to 60% lighter than metal competitors on average. Meanwhile, the expected service life is three times greater than that of metal valves. With the latest innovation, the Butterfly Valve 565, GF can provide a more sustainable, robust, and cost-effective solution for the reliable control of fluids.
*DN450 - DN600 available soon
