GF is expanding its successful 565 series with a new design for larger diameters: the 565 Big butterfly valve, with versions in DN350 through DN600*. Thanks to its PN10 pressure rating, it is the strongest plastic butterfly valve with a short overall length. The 565 Big offers a durable and cost-effective solution for demanding applications such as desalination and water distribution.
The existing 565 series has long been known as a lightweight, corrosion-free alternative to metal butterfly valves, previously available in DN50 through DN300. With the introduction of the 565 Big, the maximum diameter is doubled to DN600 without compromising the pressure rating.
Even in larger diameters, the 565 Big retains the advantages of its smaller predecessor. The body and disc are made of reinforced polypropylene and polyethylene, resulting in a weight reduction of up to 20% compared to metal alternatives. No other valve combines lightweight construction, a short overall length, and a PN10 pressure rating in these dimensions.
Furthermore, the 565 Big is easy to automate thanks to a standard interface for pneumatic and electric actuators.
