A unique feature of the NIV series is the one-piece valve stem that functions as a sealing membrane while also supporting and centralizing the poppet in the seating area. This multifunctional diaphragm/poppet results in a simplified design with fewer parts (only two for the 2-way and three for the 3-way), longer life and minimal dead volume.
Industries and applications that commonly use these types of valves to isolate gas or liquid include: drug dispensing, laboratory equipment, analytical, chemical analysis, sampling, life science/biotech, genetic research, gas chromatography, spectrometry, DNA synthesizing, blood analyzing, printing, diagnostic equipment, fermentation, water treatment and more.
- Individually controlled flow paths
- Bidirectional
- Low power consumption
- Minimal dead volume
- All wetted areas PTFE
- Ideal for gradient, mixing, and diverting applications
- Compatible with corrosive and aggressive fluids
- Equal pressure drop, response time and internal volumes
- High cycle life
- Fast response time
