- Very fast switching at a low noise level < 45 dB(A) High pressure range up to 16 bar with nominal diameter DN 1.4 mm Highest chemical resistance Compact design with 18 mm installation width High back pressure tightness The combination of maximum flow and minimum valve size is becoming increas- ingly important in various medical and IVD related applications. Combined with high chemical resistance, this explains the broad range of applications for Type 6757. However, in addition to the flow, this valve is also able to switch pres- sures of up to 16 bar. This is a highlight of particular relevance for applications in the area of environmental analysis. The devices from the areas mentioned, includ ing the valves, need to be flushed, cleaned, disinfected and sometimes even steri- lised. Therefore, they need to withstand flushing cycles with high temperatures and/or high pressure, which is precisely what the Type 6757 was designed for. The product is thus ideally suitable for applications such as endoscope cleaning or dialysis, but also for use in environmental analysers. Fast switching times, as implemented here, guarantee high process safety because reliable switching behaviour is an important aspect for accurate dosing and reproducible processes. Product variants described in the data sheet may differ from the product presentation and description. Type description Can be combined with Type 6757 © Christian Bürkert GmbH & Co.

The service life depends on the medium, temperature, pressure, sealing material and individual operating conditions. 2.) The maximum body temperature must not exceed + 110 °C. In continuous operation, care must be taken to ensure sufficient heat dissipation (convection) on the metal surface of the valve. Overheating of the valve can lead to damage. The valve must not be cycled during the flushing cycles. 3.) Measured in sound measurement chamber according to ISO3745 accuracy class 1. The value may differ under other conditions. 4.) No further power reduction possible
