The patented sealing system of the high-flow series features a swimming O-ring design. This design allows valve sealing to increase proportionally as pressure increases. Regulating the seal contact pressure reduces seal wear and fosters long valve life and reliable switching. The valves have a life expectancy of 5 million cycles.
Built with an anodized aluminum body and a stainless steel spool, the new solenoid valves feature internal parts made of brass. The valves are designed for direct mounting in any position on a NAMUR interface. These high-flow devices operate in a 22–150-psi pressure range.
The 520Di device is suitable for laboratory applications such as preparing benchtop media and reagents. In addition, the unit can accurately perform production-scale filling of pharmaceuticals and biopharmaceuticals. The 520Di machine can perform batch dispensing and automatic or single-shot dispensing of sensitive fluids in sanitary environments.
Watson-Marlow Bredel’s 520Di pump accepts eight different tubing materials and tube sizes as large as 9.6 mm. The device operates at flow rates ranging from 4 µL/min to 3.5 L/min at pressures as high as 100 psi.
