A unique feature of the PIV 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 poppet/diaphragm/stem 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. Choose from four orifice sizes available as 2-way normally-closed, 2-way normally-open, or 3-way selector/diverter.
Special configurations available by request.
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 analysis, printing, diagnostic equipment, fermentation, water treatment, and more.
For an all-PTFE version of this valve, see the NIV series.
