The NIV series is a solenoid-operated PTFE isolation valve designed for corrosive media applications, featuring a diaphragm that isolates the actuation mechanism from the fluid path. It is available in 2-way normally-closed, 2-way normally-open, or 3-way selector/diverter configurations, with a flow range of 5 to 60 l/min at 30 psig (2 bar) air. Wetted components are PTFE and FKM, with an operating temperature range of -20 to 158°F (-29 to 70°C) and pressure capability from vacuum to 30 psig (2 bar). The valve supports mounting via #2-56, #4-40, or manifold (0.118" thru hole) with port options of #10-32, 1/4-28 UNF, or 1/8 NPS. It operates on 12 to 24 VDC and consumes 1.0 to 7.2 watts. Response time is 5 to 50 ms typical. The valve is CE and RoHS compliant, and all versions feature minimal dead volume, bidirectional flow, and are fully flushable.
The NIV series media isolation valve is a solenoid-operated device that utilizes a flexible diaphragm to isolate the actuation mechanism from the fluid path. Media isolation valves are commonly used for a wide variety of applications, including those that require precise, repeatable dispensing of media for analytical instrumentation. All wetted areas of the valve are PTFE or PEEK, making this series ideal for use with corrosive media.
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. 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 analyzing, printing, diagnostic equipment, fermentation, water treatment and ultra-low leak applications.
