Butterfly Valve Type 578 :Innovation - consistently thinking ahead

GF Piping Systems Innovation – consistently thinking ahead Butterfly Valve Type 578 GF Piping Systems introduces the latest generation of butterfly valves with a completely newly developed all-plastic housing for the lug-style butterfly valve type 578. The product line type 578 unites long life circle at concurrent of low torques and offers therefore an ideal combination of quality and durability. Applications In most applications of chemical industry, chemical trade, electro- plating and power plants the transported of media is extremely aggressive. What the valve is also good for. Typical applications of the new butterfly valve type 578 are: • Industrial water processing • Water treatment • Chemical process industry • Seawater desalination • Swimming pools • Aquatic life - support / oceanarium • Surface engineering

Benefits Corrosion resistance Through the use of fibre glass reinforced polypropylen as housing material, the weight could be reduced. This simpli- fies not only the installation of the valve but also saves the storage cost. A crucial benefit of the plastic housing is its high corrosion resistance. The valve can be used reliably in highly corrosive applications. Stability and reliability The butterfly valve can be used as wafer as well as lug-style. This is a significant benefit when piping installations, for ex- ample gradually expanded, but it should already be part of the pipeline under pressure. Easy Maintenance The system allows the exchange of individual system com- ponents at any time - quickly, easily and without much effort. Technical details Dimensions DN50 to DN300 / 2“ to 12“ Material PVC-C, PVC-U, ABS, PP-H, PVDF Sealing material EPDM, FPM Montage Metric piping systems DIN / ISO Inch systems ANSI / ASME Long life time Due to the lower actuation torque, the butterfly valve is firstly easier to operate and secondly smaller, cheaper ac- tuators can be used. Since the actuation torque is strongly dependet on the internal pressure, type 578 is optimally de- signed for this area. The maximum nominal pressure is 10 bar on both sides at 20 °C. A further benefit is the long life time, since the valve is less exposed to wear and tear .
