This compact and lightweight body supports precise control of small chemical flows, and it fits easily into limited installation spaces. In addition, the design features a 2 mm orifice and a 14 mm valve width, so it delivers stable and accurate flow control. Moreover, the unit uses Flowell 80 series fittings, which simplifies connection and improves compatibility with existing systems. At the same time, an operating frequency of up to 5 Hz allows responsive and consistent performance in dynamic processes. Furthermore, the structure prevents screw loosening by changing from metal screw fixing to pin fixing, and this design choice improves long-term reliability and reduces maintenance effort.
